I'm going to share with you the differences I personally experienced between owning a C4 and a C5 corvette. hopefully this will give you information that will help you when deciding if you want to go from a C4 to a C5
I owned a 1993 C4 for a little over 3 years, it was a 6-speed car. The thing I first noticed when getting the car is that it does give you that raw feel when driving it, you can really feel the road in it and the manual transmission definitely helped. When getting in you have to drop into the seats. It's easier to get in the C5. The zf6 transmission was one of the best manuals I have ever driven, especially after I changed the transmission fluid to Amsoil synchromesh, it did shift like butter as people have said. The LT1 is a reliable performer that I didn't have any problems with. The only issue I had was with the temperature sensor in the water pump was bad which caused the car to stall and shut off. The ECM gets important information from this sensor, once I replaced it, I didn't have that problem anymore.
One thing that was in the back of my mind while I had the C4 is that there aren't a lot of people that know how to service the ZF6 transmission, with ZF Doc really being the only well-known respected source it can get very pricy. So keep in mind if you have a manual car and the transmission goes out you will have to either get a used one or have it serviced by ZF Doc. The C4 had more squeaks and rattles than the C5
As far as servicing some of the major components serviceability between the two,
I'll start out with the AC compressor it's easy to service on the C4 because of its location water pump easier to service on the C5 because as you know on the C4 if you replace the water pump you're probably going to have to replace the Opti spark if you can avoid getting it wet Ignition hands down the C5 coil over plug is so much easier to work on than replacing the Opti-spark part and I don't recall ever having to replace one of these coils on my 2002 Tahoe which now has 350k miles and which has similar architecture to the LS motor transmission the auto C4 transmission can be serviced by a lot of people but not the zf6 so I would have to lend to the C5 when it comes to this because the 4L60E can be worked on by a lot of mechanics and even purchased rebuilt. So to summarize see below.
AC Compressor - easier to service on the C4

Radiator - easier to replace on the C5

Water Pump - easier on the C5

Ignition - easier on the C5

Transmission service (manual) C5

Transmission Service (Auto) C5

Brakes - Tie


As far as the ride goes the C4 with the zf6 and the Dana 44 rear can definitely can get out the hole better than my C5 Auto with the 2.73 gears If you are looking for a car to go locally and to the car shows and Cars and Coffee then the C4 is definitely the one, if you're looking to go cross-country which is what I was looking for then the C5 is a great cross country cruiser. I flew to California to drive back to Texas, a bucket list item. The only issue I had was with the fuel gauge in the C5 which I fixed by just adding a bottle of techron. I was getting up to 30 mpg on the highway and never once did the car run hot in the middle of the summer.
The C5 I own is a 2000 convertible automatic, the ride experience in the C5 is more solid in my opinion which I believe is due to the body on frame architecture it has which is different from the C4.
The C5 has more potential for leaks than the C4, with the batwing oil pan, the axle shaft seals and output seals to name a few, the C5 also has more sensors to deal with, I am experiencing a steering wheel position sensor code (1286) that keeps coming on, I didn't have any issues with check engine lights on my C4 nor did I have issues with leaks after I replaced the transmission and master cylinder
The sport seats are much more comfortable in the C4. I also liked that the C4 had Corvette only parts and I believe the C4 was the last Corvette to not share components with other GM vehicles.
The sound system in the C5 is much better to me. I didn't like the fact that the C4 has speakers located near the floor in the front and that each of these speakers has an individual amp that can go out.
I wasn't looking for a convertible C5 but when I got one I tell you it is a much different open air experience than removing the targa top and the fact that the C5 has a trunk that is larger than I thought was a plus. The manual top can easily be retracted by one person and quicker than removing the C4 top.
The LS motor is a sweet one and I can get to 100 mph with ease even though I've only done that once ;-)
I paid 9k for my C5 it had 110 k miles on it and 8700 for my C4 back in 2021 I just got the C5 this summer
As far as the gauges I like the analog gauges better in the C5 and the 200mph speedo is cool.
I don't know why the C4 gets such a bad rap, I remember back in the early 90s I had a LX 5.0 Mustang and I thought I was the fastest thing in town until I came up against a Impala SS LT1 car it passed me up like I wasn't even moving and I was going pretty fast also the LT1 was used in countless taxis and police cars so its a proven performer. I think the optispark issue is overblown and it's not that hard to replace. C4 owners are getting well over 100k miles on the original units.
One thing I didn't like about the interior was the door panels on the C4 because the top portion of the door panel cannot be secured with Clips it's basically secured by the lip of the door panel resting in the window channel, over time the top of these door panel pull away from the door, this is a non issue on the C5.
The one thing that the C4 has over the C5 again is less electrical issues to deal with, the C5 is has more sensors and modules at the than the C4, for example the ebcm in my model car is a $1,000 used part this is not an issue with the C4 also the harmonic balancer can become an issue in the C5 I did not have to worry about that with the C4
My recommendation is to buy a private owner car, they can tell you the history and be prepared to go out of town if need be I found my car on Auto Trader
The body panels on the C5, the fender Hood Can be easily replaced whereas on the C4 you have to replace the whole front clip if that gets damaged, my C4 also had selective ride and those replacement shocks can cost several hundred dollars so I would recommend staying away from them in both the C4 and the C5
Another thing I like about the C4 over the C5 is the door panels had two sets of Lights one for when the door is open and another driving light Amber that comes on at night it really shows to the detail GM hat when building these cars I think the interior even had Lights under the console in the middle also the C4 has a spare tire while the C5 does not
Performance wise definitely the C5, but the C4 is good enough in my book it's just that the C5 has much more aftermarket support whereas you can bolts on a supercharger and be easily at 500 horsepower. I read where somebody considered the C5 as a Swiss army knife. It could be a track monster or a cruiser or you can go to Cars and Coffee and feel at home. You could even daily drive a C5. The C5 on the highway to me feels more comfortable and is a smoother ride.
I love both cars but the C5 was better for me. I was going to go from a C4 to C6 but the prices for a good C6 are out of my range right now. Hope enjoyed this summary, save the wave!

 

Nice review and thanks for taking the time to share your thoughts. I owned four C4s (84, 89, 94 and 95) and also three C5s (99, 00 and 03) and while I liked each car in its own right, my personal opinion is the C5 is a much better platform - better ergonomics, more performance, less overall parts to break, and a better aftermarket support for upgrades. Others may disagree with that and that’s OK - everyone has their favorites and opinions.

Whichever way one goes between the C4 and C5, the cars are a blast to drive and reasonably priced for the performance you get.

 

Nice read - thanks for writing it. Always liked the 4's and would add a 96 to the stable if I could.

 

The C5 is just a better all around car. Just read All Corvettes are Red. Their goal was to supersede the C4 in all aspects where it failed.

The reason it is better they had more time to develop it and they had less interference since they had to hide the program.

 

I have to read that book, can’t believe that the Corvette almost went out of production!

 

The truth is it was dead. If not for the engineers ignoring GM management it would have been killed.

GM did not just go broke in the early 2000's. They were hurting for money as late as the late 70's. Most people have no clue how bad things were. As for the C4 it was not selling well and it was not making money. The Corvette like any other car is required to show a profit.

GM is in better shape now than most automakers but they are all facing a very tough future here. Even the dealers are selling out and merging.

 

Hyperv6 is spot on. GM management made some pretty bad decisions in the last several decades. The big problem is that they are still making them. While I realize we all make mistakes, with the Japanese auto industry starting to really squeeze domestic manufacturers, every domestic auto manufacturer has less margin for error in making management decisions than ever before. Bad management is what took Packard down. GM, Ford, and Chrysler aren't immune from going down the same way. GM and Chrysler have already filed bankruptcy once. At least C5 owners don't have the LS7 debacle hanging over their heads, which is another HUGE ball GM management dropped.

 

I sometimes wonder where the Corvette is going. Very high tech, expensive to buy and repair and the more complex they get the more the to go wrong, but I guess they still sell well. When I read comments saying I wouldn't own one out of warranty it makes me wonder.

 

As far as not owning one that's out of warranty I highly disagree when it comes to a Corvette, I have heard people say that a lot when it comes to BMW's. All C5's, C6's and Mostly all C7's are out of warranty yet owners are loving them every day. Most repairs are not that difficult, their is a lot of support out there, especially this forum! With tons of videos and manuals out there you can do most repairs yourself. Yes some parts (1997-2001 Ebcm, sps) are expensive for C5's but most owners of 1997-2000 C5's haven't had the Ebcm problem and I am one of them. When I hear people say stay away from these models, if its a good deal I wouldn't think twice about getting one as I did. I had an issue with my sps throwing a code but I was recently able to fix it by just disconnect the steering shaft from the gear box and rotating it 360 degrees. This is just a small example on how easy these can be to work on and the experience of owning a Vette is priceless!

 

GM has made many mistakes in many areas. But today they are getting most of it right. Yes they still make mistakes but few are fatal. In fact the investors recommend few automakers for investment but GM has been one they recommend.

We will see many changes in the future. I would not be shocked if GM and the auto industry follow a path of electronic companies. They build, design and engineer a product but they let someone else MFG it. Case in point the Apple Phone. Apple does all the development but the MFG is sent to companies like Foxxconn. Then they also use parts from suppliers like Samsung for the screens built to their spec.

So much is in flux right now as we will see more mergers. partnerships and failures of some old names. But GM even in tough times is still making money.

 

The Corvette has never really been cheap. It always was the most expensive Chevy till now the trucks and SUV cost more.

The Stingray is a great car for a very good price. Now that prices are getting back to below MSRP like we are used to they are down right bargains. I see them in the $60K range and that is a steal in todays market where a Canyon Denali could cost me $60K too.

As for repairs. All the cars are getting more difficult. But like in the past like when the C4 came out everyone was like we are screwed will never figure this one out. Then the later cars came and same was said but in the end we who wield wrenches figure this out.

I own a mid engine car too and everyone makes such a fuss how hard it is to work on but the truth is it is no more difficult than most FWD sedans today. The engines drop out the bottom and yes you may need a lift but generally they are not hard if you just learn what you are doing.

The other issue is often parts being available. The one thing the Corvette enjoys is the number of cars built leave many replacement parts used and also give a good market for reproduction parts. Yes now and then you get shorted on a part but often most needs are met at somepoint or a solution is offered for sale. We are now seeing F45 shocks now coming out. Not sure how good they are but they now can be purchases. Simulators were offered too.

The truth is the Stingray is what most of us will buy and if you can afford the ZR1 then you will be able to cover the added cost of these more complicated cars.

Even a 308 Ferrari is not hard to buy but unless you know how to work on one you will go broke. Same could be said for a C5 if you have to pay someone to do it.

Nothing is cheap anymore but the Corvette is still the same price segment of the market it always has been. Just because the cost of living has not kept up is not the cars fault. GM has done a hell of a job not selling it for more.

 

For me each generation has its pluses and weaknesses. Owning both a C4 and a C5 I get to enjoy both equally. Having owned sports cars, both domestic and foreign, and muscle cars from the 60s and 70s each has specific repair requirements but that is a cost of enjoying automobiles as a HOBBY.
The C4 is like driving a go cart on steroids. You feel every bump and pothole in the road but it gives you the analog feedback the same as driving an MG or AustinHealy but with a lot more power and handling. I love it every time I drop down into the “cockpit” feel of the C4. Of course the C4 is not a car the wife and I would take on an extended road trip due to its lack of comfort but to put the top down and enjoy driving it on country roads it is hard to beat.
Now the C5 is a pleasure to drive. Smooth, powerful, comfortable and with less squeaks and rattles than the C4. A simple grand touring automobile that is available for a more than reasonable price. Does a newer C7 do all of this with more power and handling performance? Sure, but it is not something I need or think warrants spending three times what a C5 costs.
In the end it all comes down to personal preference and how you want to spend your money.

 

To me the C4 makes you work to go fast where the C5 makes it easy to go stupid fast over the same path. And the C5 does it mostly eith out computers vs the c6 and 7.

The key is the stiff frame this is the foundation of any good handling car.

 

What I was referring to was the C8 and the future of the Corvette. I read lots of those comments on the C8 forum. When a transmission is costing $20,000 out of warranty it makes me wonder. No way would I buy one with higher miles on it with with the electronics it has. A 20 year old C8, oh boy. Now maybe I'll be proven wrong, but when that E-Ray starts having problems better start the oil well back up! And I don't read about too many C7/C8 owners doing their own repairs.

 

I have a 95 C4 and an 02 C5Z, sure the C5 is better in most ways, but the C4 is more fun, more race car like. They are both heavily modified, so a lot of the weaknesses have been corrected, but if stock the Z would probably be more fun. The ZF6 in the C4 is the best shifting manual I have ever tried, much smoother and precise than the Z, even with an MGM, weighted shift ****, and Anti-Venom, but that may be my specific car for the Z. I have 140K on the C4 since buying in 96, and put on 127K of those, and has been a great car, no drive train issues ever.

 

You are spot on about the ZF6, I wish I could have kept my C4 but I can only afford 1 vette. I could burn rubber and get a little sideways in the C4, not so much with the C5, with the 2.73s in the back there is not much spinning the tires but it sure can get to 100mph quick!

 

Gee no spin and a fast pace to 100 mph. You might really think about this.

GM spends a lot of money designing these cars to grip not spin because it is how you make the car faster, Aldo it jeeps you from looking like an A hole crashing with the Mustang guys.

A well tuned and sorted car will not jump out from under you. It makes going fast feel slow.
