You got that right. An 87 Buick is not a “muscle car.” Nor is it classic.
Okay, just give me one cause they ain’t that great. Funny thing is, I had a ‘97 Pontiac GTP with the supercharged 3.8 front wheel drive that was nearly as fast as the GN’s.
You apparently didn't spend any time at the track in the early 90s. Mild tunes were pushing them well into the 12s.
Every drive one or get beat on the street by one? In 1987, I was driving in my Ford sedan with police package V8 and suspension and stopped at a light. Next to me was a brand new Buick Grand National. It was drizzling and the road was damp. When the light turned green, I stomped the go pedal and the car launched perfectly since it had a limited slip and big Goodyear Eagles. That Grand National had me by ten cars in about three seconds. There are now collectible enough that a pristine very low mileage GNX will do mid hundreds at auction. As I recall, they were in the high 20’s to low 30’s when first introduced. The only 60’s muscle cars that would keep up (stock, that is) would be 427 Corvettes, 454 Chevelles, hemi Mopars and, of course, the few real 427 Cobras. The original Porsche 911 Turbos would only catch and pass it over 100 mph.
In this case I am sorry but you are wrong. The Grand Nationals are very highly valued collector cars.
