Also it looks like the prices probably wont get much lower than they are now for these C4 Zs so I see no need in waiting much more.

Thanks again for your input!
I would take a hard look at Johno!'s '91 ZR-1. It is tempting me but I'm just not in the market at the moment

David Fultcher is the MAN!When I had a completely dead ABS system in my 91,when I called all of the best ZR-1 Techs,most we know by first name,paid Gordon Killebrew $40 for his tech advice over the phone,it was David that walked me through the system and helped me find the problem,all over the phone and most of the time he was at work.Never once did this guy get annoyed with me calling him,not once.

The 1990 LT5 has no valve stem seals. Smoke on start-up is the result...that's the "issue".

Default Computer Issues

When I had a 1990 ZR-1 inspected by the best Corvette shop in the DC area, it had an airbag light lit up in the little screen that would not go out. In Virginia, the car would not pass inspection unless the computer was indicating the airbags were working. The fellow told me that GM no longer makes the replacement part, that it would be necessary to get it as an NOS part if it could be found and that it could take many months to find it at a cost of, as I recall, of up to $2,000. He generally warned me off of the early ZR-1s because parts are hard to find. He said to get a 93, 94 or 95. It was enough to scare me off the car.

You just wrote the biggest misconseption about ZR-1's....

Parts are not hard to find. Love to hear the name of "the best Corvette shop in DC" that couldn't troubleshoot the airbag light.

David

The ZR-1 uses the exact same airbag light circuit and sensors as all other C-4's.
Nothing unique or different here.
Perhaps that shop should stick to minivans and any remaining Vegas that are out there, and stay very very far away from real cars.
Some mechanics! Can't fix stupid.

It's a shame you allowed yourself to be "scared off" by misinformation.

Your kidding right! I am looking at a 250,000 mile LPE car to purchase as a project. I have heard nothing but great story's about the LT5 engine.

Heck , my modded ZR1 is used as a DD and is dependable as can be. It's not used in the snow-ice.

Ground for those gets a little corroded and the light comes on thats all it is. Happens on almost every 90 Vette. Clean it and youre good to go.

Some expert he is, kept you from a great car.

It should do 5K a year forever. Lots of folks have over 100 and even over 200K on them.

True, although some are worse than others. Either way, I wouldn't let it scare me away from buying a '90 ZR-1 as I don't see it as an "issue", just normal for that year.

On the exhaust valves that is.

I never really see any "smoke" on my 90 until I get into it and thats another issue entirely!

What a crock.

If VA is a "visual" inspection state Take out the damn light bulb.

and its a airbag jesus when did everyones vaginas get all full of sand.

Check EBAY for airbag parts. I think you will be suprized.

and It probably was just a damn ground issue pathetic Best Corvette shop my ***.

don't sugar coat it Phrogs, tell us how you feel!! I agree, many of the so called corvette experts can't spell LT5 and when you hear "gee I've never worked on one of those" when you roll in hit reverse and the gas

there are TONS of very knowledgeable ZR-1 guys in the registry. Phrogs is one of them.

seek them out,, they can help you. also know that fixing a ZR-1 is less complicated than a new honda or bmw, audi or any of the new cars for that matter.

people see a vette with a DOHC engine and run. the LT5 is a very simple engine. the rest is a standard c4 with some wider hips

don't fear the zr-1, it's more reliable and I've had less problems with it than I have anything else I own, including my C5

Finally in the new house and got a few little issues to work out. But I hope to pull the trigger by the end of the week.

I would take a hard look at Johno!'s '91 ZR-1. It is tempting me but I'm just not in the market at the moment
I will do that. Thanks for the heads up. One thing I have noticed is that you ZR1 owners are a tight nit group of folks and thats encouraging especially when buying a car that is rare.

Yes the LT5 group is very tight knit. And we all watch each other's back. A brotherhood if you wish.
There are quite a few real nice car's on the market right now.Plus being in a buyers market , you da man ! If you are in the Georgia area there is a great group of guy's there. As well as a top knotch wrench in the south west corner of the State.
Either way......happy hunting

I went the C5 route after my LT1 but should have gone with the ZR-1. The group is much more tight knit and IMO the C4 chassis is much more rewarding to drive.

If SGC has their fall get together it is alot of fun.
