It's been mentioned but this isn't apples to apples, there were what, less than 50K total Turbo (intercooled) Buicks made (86-87)? And there were what, several MILLION foxbody stangs made? It's irrelevant, a foxbody stang in GOOD shape is worth what, 4 or 5K at most, a ragged out GN will bring 6 or 7K (add a 1 if it's in good shape) because it's rare.
If I want to go fast cheaply I'll sell my GN and get a foxbody mustang, those babies are hard as hell to beat in the "go fast cheaply" market. If I want to go fast AND draw a crowd whenever I pull into a parking lot, or a car show, or anywhere else, I'll take a Grand National. There's no argument, the amount of technical expertise out there for a foxbody is way way way more than there is for a turbo Buick, there's probably 100 TIMES as many of them on the roads as "us". Since I bought my GN (in July or late June forget which) I've seen -3- other turbo Buicks, 2 at the 2007 Ardmore car show and the GN that Frank Gordon owns that he got from Nguyen, the one from Pinks. Foxbody stangs? I dunno I don't PAY ATTENTION to them on the road, do you? There's my point I guess. I've not seen another one, on the road, period, in 3 months. I can't count how many foxbodies I've seen, because I don't pay attention to them when I do see them.
Those Mustangs are very hard to beat when it comes to going fast in a straight line dollar for dollar, for the price I paid for my GN I could buy a Mustang, mod it, tune it, and get it way faster than I even HOPE to get my GN before I even spend as much as I paid for my GN to bring it home.
Some comparisons are best left uncompared. If you DO go faster than a foxbody they'll just pull out the "yeah but how much did you spend to go that fast?" argument. There's simply no Mustang (pre 1974) on the road that'll make me feel like I feel when I drive my Buick, even if it isn't that fast. I like my Buick, I wouldn't trade it for a half dozen Mustangs from the same era.
