1985 Grand Prix concept car?

I thought 2+2 meant it had the aerocoupe back window?

There were 1 or 2 2+2s built like that in that year for GM executives. I believe that the 16" rims were added later. As stated previously, I would insist on documentation to verify that the car is the real deal before laying out that kind of money.

I'd like to see the VIN/serial number stamping as well - I don't know much about factory prototypes, but if that matches what typically happens with such cars, you're one step closer to authenticity

Authenticity is the deal breaker here. You can replicate a GNX too.

I have a question! Didn't GM sell bodies that were called "BODY IN WHITE" and that had no registration VIN numbers? These bodies were sold to racers and the like for special off road racing and to builders to build concept type vehicles (that were to be distroyed after their use? I know some "BODY IN WHITE" bodies were sold to prostock drag racers!
These bodies were painted entirely white.

Just asking!

The rear spoiler looks like it could have come from a Lumina! LOL

The spoiler actually looks really nice, as if it belonged on the car.

I don't see a thing about that car that doesn't fit exactly what PMD would have done in that situation, it wasn't a show car, it was a prototype, for testing a nose and spoiler to see if they could the results they wanted without spending the big money on the bubble glass. The VIN, EX4788. It fits into normal GM nomenclature for such cars, the white trunk doesn't mean a thing, the car was painted in the specialty shop where the nose and trunk were done, common practice, I'd say it's real.

if it is a prototype and was used for testing and it comes without a title then why does it have over 15 thousand miles...the main reason they put a long window in the back was to stop the rear of the car getting lifted from the vacuum that was created by the flat back window, which in turn slowed the car down. Even the rear spoiler on the nascar body didn't help that problem so I don't see how that low rear spoiler had any effect on the problem they had..plus with the suspension on that car I don't know what testing they actually did with it sitting so high..

I think the thing that has everyone stirred up is the fact that he wants $18K and he doesn't have the documents to back his claims. The whole idea behind rarity and authenticity is PROVING that you have the real deal. I say he'll either find a sucker, someone who just loves the car that much with money to piss away, or someone that knows the intimate details behind this car will buy it.

i think it's sweet looking GP, I have considered building my 85 with the 2+2 nose i found this drawing which looks BADASS

and another pic i found of the GP on craigslist....

Well, let's start with the miles, super easy answer, GM VIP's could put a manufacturer's plate on a Go kart and drive it if they want to. The vin is standard fare fore cars not intended for production. Now to that little spoiler and how it might help. In the old days we called it moving the bubble. That meant that by extending the trunk back and/or up into the slip stream, you could actually move the air stream higher off the rear of the roof therefore cutting down on the low pressure area behind the back glass. That reduces the drag coefficient making the car faster on straightaways. Now obviously, if this was truly a PMD prototype, it didn't work well enough as the bubble glass showed up shortly after this car. I have no idea if the car is real, but nothing about the car precludes that, as I said before. When I say things like that I'm not pulling info out of my *ss, I'm telling you from what I've known to have been facts in the past. GM and all th rest did stuff like that in the 60's and '70's, why not in the 80's? This car might be a total hoser, but nothing about the car I see or his info proves that to me. I assume he or someone has the bill of sale from GM, if so that is likely all the docs that exist. If nobody can produce the bill of sale, then it's just a leap of faith.
