I love em.....always have. Of course I was also 17 in 1987 when these were roaming the streets. They were the first American Muscle car in ages that could run with the cars from the 60's. Keep in mind, growing up in the 80's, we weren't pining for new cars.....we were lusting for the Hemi Cudas, SS Chevelles, and GTOs of the late 60s- early 70's. Nearly all cars were dog slow.....with a 16 second 1/4 mile being seen as quick. Here comes the intercooled T-Type and GN, which could run mid to high 13 second 1/4 miles......bone stock! They were a revalation.
We quickly learned to keep an eye out for the third tail-light, which was mandated in 1986. If a GN had one.....watch out, it's an intercooled car, and fast! If it didnt'......no sweat, it was an older one, and only capable of a high 15- low 16 second 1/4 mile. The fast ones also had those ugly steel wheels--- although you could still get the "turbine" wheels on the T-Types. Those T-Types were the real sleepers, as you could get them in colors other than black. Sneaky cars that looked alot like the Regals your grandma was driving.
Keep in mind, those 80's Japanese cars we now lust over, like the Starion Turbo, Second gen Supra, and RX-7 would take 15 to 16 seconds to clear the 1/4 mile. Yes, they handled better than the GN, but on anything but a twisty mountain road, or a race-track, the GN would humiliate them. The GN was even quicker than the Corvette, the Ferrari 308, or Porsche 911 of the day.
I remember the first time I saw a genuine GNX on the road. We followed the guy, trying our best to get him to floor it.....just so we could see it in action. That damn responsible bastard wouldn't fall for it.......but we did gape at his car for a good long time.
It's hard to explain how cool the GNX was........ at the time we all thought it would be the last true Muscle car, as everything was headed for FWD. GM thought so too, and they allowed their engineers to have some fun. It reminds me of the Demon and Hellcat these days---- one last F-U, look at what we can do---- before the autonomous cars take over.
