My uncle owned a 1986 Buick Grand National, really slick, with the big engine. He had worked for years in Detroit in the auto industry. A few years ago, shortly before his untimely death, he mentioned he didn't need it anymore. Unfortunately, before I could make an offer to buy it off of him for my son (who was going to help pay for it and wasn't yet driving), it was stolen and never recovered. My son would still like to get one when he gets older.
In college, I drove my friend's older brother's car. She had it on loan, but hated it. I wanted to buy it, but the brother's b*tchy fiance sold it at auction for about 1/4 what I was willing to pay, me and the other interested party. It was a 1971 (or poss '70) Challenger with the 340. It was great to drive.
Now I guess you know that buck grand nationals really didn't have big motor's, they had turbo's.
