My Father-In-Law has what he calls (and has been told) a "Prototype Corvette". I believe the corvette to be a 1982 model. The thing that makes it stick out is the unique rims and the fact that the back end is one foot wider than the front.
I'm not an expert, but I believe the back end is part of an after market kit.

 

Try posting in the C3 section

 

That was the first prototype for the 6th generation we now know as the C6. This is a good example of how long it takes to get a car to market. Your Dad is right, and that car would probably go for close to $2 million at a place like the Barrett-Jackson Auction. It's too bad they didn't go with those rims, they are sweet. I certainly hope this car has been kept off the road & under cover. It is far too rare of a find to have been abused.

 

You are probably right......

 

Kinda useless post without pics

 

Or a link.

 

Might it be the Duntov Corvette?

 

Wow, that brings back some memories. I got to actually ride in one about ten years ago. It would be nice to know how fast it was, but I'm guessing it was a low 12, high 11 second car. The unique thing was this was about 5 years before the anniversary turbo T/A that came out in the late 80s. At the crank the prototype was a twin turbo rotary with pistons. Incredible machine, I'd do anything to have it.

 

I was pretty sure that's what it was running but I didn't want top spec it and get flamed if it wasn't. Thanks for the insight.

 

Prototype? The prototypes I interacted with while I was a test driver for GM were VERY EARLY cobbled together shabby looking versions of the eventual refined production versions. I think your Father-In-Law is trying to say he has a "concept car" by his noting of the styling differences. Without knowing more I feel it's safe to say his car is a regular run of the mill production Vette with an after market body kit installed to customize it.

People can say they have anything, and in some rare cases they may have something, but it's all worthless without DOCUMENTATION. You can tell Dad I said that. GM is not one for letting their prototypes or concept cars get in the hands of the general public. The Corvette concept cars on display in the NCM in Bowling Green are on "loan" from GM. If a GM concept car, especially a Vette, was in the hands of a private owner, it's worth an AZZ load of money, and chances are Daddy-In-Law could not afford to acquire it. That's big time Barrett-Jackson stuff. See this privately owned GM/Oldsmobile Concept car?:

It sold for $3,240,000. last January. Does your Father-In-Law have the kind of $$ that he can be buying Vette concept cars?

Here's what happened. Father-In-Law decided he wanted a Corvette even though he knows nothing about them. Somewhere in his search he encounters one that looks different than the others he's seen on the road. The owner of the car spots his ignorance and proceeds to tell him it's a "rare prototype", and jacks the price up on something that is in all reality worth way less than a 100% original stock example of an '82 Corvette because it's been butchered up. Go to eBay. There are a lot of custom Vette abominations appearing there all the time.

Post some pics. If he has documentation, post it. Otherwise he's got

 

It's a '83
