Deciding between NOM or Original C3?
Which do you want? coupe or convertible? For just a nice driver, there's nothing wrong with something like your '72 if it is in good shape. Lot's of money left over for any unknowns.




As said, buy the best car you can afford. And, a few more dollars for an original motor is worth more than cosmetics. While I believe in paying for cosmetics, its possible to buy new paint and interior. It is not possible to buy an original engine... that value will never be available again.
NOMs are poor investments,although it's an option if you are on a low budget.
Vettebuyer has some good advice. Buy the best car you can afford, one that needs the least done to it before you can enjoy driving it. Pay for it now or pay for it later. These cars vary widely in the price of admission, but the overpriced goodies at the concession stand pretty much cost the same for everybody..they quickly add up and can total more than your ticket to ride. Enjoy the show!
The 69 is right about it's top value point, so for that price, it should be in very nice condition. If there is anything wrong with it, I would question the price.
The 72 is right at the price you would expect for a NOM in nice condition.
The 70 convertible has quite a bit of upside. A nice, original engine, driver 70 vert should easily be in the $20-$25 range. So there is room there for paint, and a new interior. But if it needs those things, what's the shape of the rest of the car?
If you want a convertible, I'd make dang sure it only needs paint and a new interior. And, if that's the case, it's not a bad deal.
If you don't care about getting a convertible, then I would go with one of the coupes. The real difference I believe between the coupes is what you plan to use it for. If you want a car for weekend cruising, and a car you can pampler, go with the 69. If you want something that looks nice, but you don't have to worry about when you drive it, go with the 72.
I agree with many of the points that have been made.
My addition is to think long and hard about a coupe OR convertible!!!
Yes, the coupe's roof panels come off, but it's still VERY different than a convertible.
Good Luck!

you can get your money back for a NOM car and you don't have to worry about nursing the engine along. Just pay the right price.
you don't have to worry about whether or not it is truly the original engine either...

Thanks for all the input so far btw.
but do you only require the engine block to be original? what about the carb, heads, intake, exhaust, wheels, glass, interior, transmission, rear end?? what is your definition of original?
just because the block has correct numbers ( original or non original restamped) does not mean it has the original heads, intake, tranny, etc.
Only go with a numbers matching car if you really want one and wish to keep it that way. Otherwise, save the money or just get a car in better condition.
DO NOT buy a car the "needs paint" unless you can do the painting yourself...or you have a lot of money (and from your post, it doesn't seem that that's the case). Having someone else paint the car is expensive and troublesome. Get one with a good paint job or one with a 'decent' paint job that just has some minor blemishes which you can 'touch up'.

My take...
I'd say much depends on whether you're interested in restoration or looking for a driver which you may possibly modify. If restoration to original is your goal, originality is very important. There is a way around this if you find a date correct block and restamp. It's been done many times unfortunately. This raises ethical questions and is another hot topic. An 'original' will often cost more than a NOM in comparable condition. To maximize the value of an ‘original’ the car must be kept as it was built. No color changes or upgrades and lots of documentation if it’s a high value version, LT1, LS5, LS6, etc..
So far as values go, opinions vary depending on which side of the divide you are on. Many who bought a 'numbers' car in the last few years probably paid a premium for them with the expectation of getting a much better return in the future. This has been true up until recent years when the economy crashed. I suspect there may be many who may be further under water today with a 'numbers' car if they bought at the peak a few years back. Values may come back or may not, pretty much speculation. So far as NOMs go, I've seen some sell for far more than the numbers people predict they should. I've never seen any reliable data on how much an average NOM actually sells for compared to a 'numbers' car in comparable condition. It's pretty much speculation. The majority of Corvettes listed for sale are ‘numbers’ cars, tough to get a feel for what the average sales price for comparable NOMs may be. Raises the question did only a small number of Corvettes have an engine changed in the last 40 years +/-? I believe it's true, historically, that a true original will go for more but how much more depends on many factors. On the other side, if NOMs never gained in value there should be some pretty nice ones out there for virtually free. If the actual difference in % appreciation over a period of years for a numbers vs a NOM is small, you may do as well taking the difference in purchase price and investing the money elsewhere. It’s possible you may do even better if the investment earns a better return than the car does, diversifying. Another question is whether the trend will continue indefinitely? The cars are growing quite old. Will they be practical to drive much in future years with their stock drive trains? Will fuel become an issue? How about quality parts? These are some reasons why a modern drive train transplant may become more desirable in the future if the car is going to be driven.
Whether you buy an 'original' or a NOM, the advice to buy the best car you can find is sound. There are gems as well as pieces of junk in either category. The presence or lack of numbers alone doesn't guarantee anything wrt the quality of the car.
If you're planning to keep the car only for a short term, maybe just a few years, I can't imagine the difference in appreciation is going to amount to that much money if anything at all depending on market conditions and how great a deal the buyer got when the car was purchased. For a long term restoration project, the difference may be more significant. In that case I can see the difference in resale price helping offset if not pay for the restoration, providing the buyer is interested in preserving the car in the exact configuration it was built.
I don’t believe a ‘numbers’ car is the best choice for all buyers regardless of their goals. If your interest is in vintage Corvette restoration, maybe shows, originality is the way to go. If your interest is in a restomod, a numbers car may not be appropriate. A NOM may be an option for those who want a high end drive train but can’t afford the high prices for an original or aren’t interested in spending that much money. As others have said, there’s more risk driving a high end original compared to a NOM. An accident or damage to key engine components may wipe out a lot of the added value.
Ok.. here we go:
So- the whole NOM vs Matching.. ya know, when these cars were first built, no one really gave considerable thought to whether or not when an engine had issue as to whether changing it would hurt the value later. It's not until the last 10 years or so that the whole numbers matching "thing" has gotten twisted out of hand.
Yes --- cars that are truly numbers matching.. and i mean validated, verified and most likely NCRS vehicles are going to increase substantially and could be considered appreciating investments...
HOWEVER ---
I've seen some "matching" cars that are in **** condition. And the cost to fix them would exceed the ultimate value. For $12 - $14k, the net difference in the value isn't worth fretting about.
There's also something to be said about "numbers correct" vs "matching". Is the NOM your looking at have a Vette Engine from the same year? Not uncommon. Some of these engines there was no way to "rebuild" so they HAD to be replaced. Just reality. I would not get too hung up on the NOM thing -- you just need to decide how far NOM is acceptable. Is an engine from the same era ok? Will you accept a new crate motor; Or is the absolute original motor the only thing you'll allow.
If you're buying an LT-1.. then matching is probably more important. Base 350.. ehhh.. not gonna matter much. A nice Vette is a nice Vette.
I can assure you.. the cost of putting these cars "right" is not inexpensive. I would buy the car in the best possible condition in the color you like and try to stay as close to original as you can -- but some stuff may have to give.
good luck with it.
