When I was a lot younger, a friend of my Dad's was this doctor. He loved cars, he had like 25 or 30 cars at that time. He would just spend tons of cash on cars he didn't even care lol. I was too young to drive but I got to ride in a lot of his cars and of course was blown away by his collection, which seemed to change weekly. That lucky bastard lol.
Anyways, he bought a Grand National, right when they first came out, and had ordered it with all the options the way he wanted it, except he wanted it painted beige and with a vinyl top. The dealer would not do it. He offered them some ridiculous sum of money to do it, like 10 grand in today's money and they still would not do it.
So he had to take it to a body shop to have it painted, and a vinyl roof put on it. The reason he wanted it painted is because he also at the time had a black, flamed 70s vette with nitrous that he claimed got up to 180mph. Well good old Johhny Law got him and let's just say a very LARGE fine was handed out. So he almost didn't buy the GN because of how it looked, he knew he'd be a sitting duck for LEOs and didn't want any more bad tickets.
So he had that GN painted beige, with a brown roof. It looked just like a regular Regal, it was the pure definition of sleeper and I think he put the bottle on that car too LMAO. To see it launch was just hilarious. I mean the natural reaction was to just burst out laughing at such a spectacle.
The guy is still around, his collection is smaller now, I think he sold off all but the Vipers and maybe a Shelby or 2.
