Gnx #239

Is available for $30k. A little high, but like like the fact that it's been used. The other 546 are garage queens.

Buick GNX #239

[BlueSkyJaunte]

What a hunk of crap!

[speeder]

Yep. I have no desire to own that even if it were $1000. What a toilet.

[onewhippedpuppy]

YGBSM. $30k. Wow......

[fastfredracing]

Wow, have they gone up that much in value? One of my porsche customers was trying to sell his, which was 10 x nicer than that rat, and it festered for a long time at 10k.

1987 Buick GRAND NATIONAL

[GG Allin]

You guys are confusing a GNX with the Grand National. Nice GNX's typically sell for around $60k to $100k.

For the final year, 1987, Buick introduced the GNX at $29,900. Produced by McLaren Performance Technologies/ASC, Buick produced 547 of the 1,547 WE4's with the Grand National interior trim Package. They were then sent off to McLaren Performance Technologies and upgraded into the Buick GNX. Buick underrated the GNX at 245 hp (183 kW) and a very substantial 360 lb·ft (488 N·m) of torque.[5] This was created to be the "Grand National to end all Grand Nationals." Changes made included a special Garrett T-3 turbocharger with a ceramic-impeller blowing through a more efficient and significantly larger capacity intercooler with a "CERMATEL (Ceramic/Aluminum) coated" pipe connecting the intercooler to the engine. A GNX specific EEPROM, low-restriction exhaust with dual mufflers, reprogrammed Turbo Hydramatic 200-4R transmission with a custom torque converter and transmission cooler, and unique differential cover/panhard bar included more of the performance modifications. Exterior styling changes include vents located on each front fender, 16 inch black mesh style wheels with VR-speed rated tires, and deletion of the hood and fender emblems. The interior changes of the GNX included a serial number on the dash plaque and a revised instrument cluster providing analog Stewart-Warner gauges, including an analog turbo boost gauge. Performance was measured with a quarter mile time of 13.2 seconds at 104 mph (167 km/h) and a 0-60 mph (97 km/h) time of 4.3 seconds.[6] GNX #001 is the 1986 prototype currently owned by Buick and sometimes makes appearances at car shows around the US. The GNX had a ladder bar that ran from the midsection of the car to the rear axle, so as to increase traction. This is also the reason why a GNX will actually lift the rear end up when the car is about to launch heavily.

I've flushed things that looked better than that car, and I'm a turbo-junkie.

You need to drive one that's been slightly modified. They are ridiculously fast with just software.

[creaturecat]

too funny.
i respect the fact that it has been driven into the ground. where it now belongs.

Per Hemmings--average value for a GNX is $108,000.00 Who Knew?

And unfortunately there is no way to know what one that's been restored is worth. 99.9% of them are original with virtually no miles. To restore one would not be easy or cheap. Parts are surprisingly unavailable and or expensive. I'd be a buyer at about $10K or $15K for this one.

[asphaltgambler]

There was a local guy who bought one new (left the window sticker on) and would occasionally show up at the car show scene. I remember the sticker numbers was north of $40K + a huge dealer markup over the sticker. I never asked what he paid but adding an additional $10-12K is prolly about right.

The GNX is THE GM sleeper from the 80's. A true wolf in sheep's clothing. IIRC, they shoe-horned the same or similar motor into the GMC compact pickup truck and called it the Cyclone - fast as a Vette, even in the rain and snow!

If that is a true GNX (and not a 'clone') it could be worth the $$ to restore - but not my money. Though I appreciate & know about th car, I'm not a follower or fan.

-Z-man.

[asphaltgambler]

The Cyclone actually had a chevy 4.3 V6 (3/4 of s small block) where the GNX had a 3.8 Buick based V6. I've worked on a drove two Cyclones which by the way were all wheel drive!!

They were stupid fast for the time and really way ahead of others because it was the only GM product with all wheel drive. The transmissions unfortunately were not up to the task even with bone-stock applications; BIG torque and major traction= finds a weak link. My opinion is they were much faster than the GNX's

Syclone. And the Jimmy version was called the Typhoon.

[Steve Carlton]

A friend of mine had the Syclone, then later a GNX. He was an accomplished drag racer and owns an indy MBZ repair shop. The Syclone got heavily modified and when launched from moderate revs by releasing the brake, the thing felt like it was launched by a catapult. I remember one of the car magazines said something like '0-60 in 4.1 seconds- in the rain!' IIRC, the Syclone had a Corvette automatic transmission. There was also the Typhoon, the small Blazer version of the Syclone, which was a small pickup truck.

[speeder]

A friend had the Typhoon and I thought it was tight. I'm not anti-GM and I always give them credit when due for a cool design, but I always thought that the Buick GN and GNX were toilets. Sort of the automotive equivilant of the old Suzuki 500 2-strokes from the late '60s, super fast but still junk right out of the showroom.

[Steve Carlton]

Well, they were basically Buick Regals, although the GNX had some appropriate upgrades. There was an anniversary Trans-Am that had that motor as well that was very fast. I always thought a sleeper T-Type would be cool as a DD, but I don't think they sneak under the radar cheap.
