1987 Buick GNX

It came to my attention on Friday this unbelievable 1987 Buick Grand National GNX on Craigslist. First a little history on what exactly the Buick Grand National GNX is and why should you be completely in love with this car. The GNX was essentially meant to be the end all of Grand Nationals. Claimed to be the fastest production car at the time it was quite a car. With a price tag of $29,290 this was a very expensive car for the time. Rated at 276 HP and 360 lb-ft of torque all flowing to the rear wheels from a turbo charged V6. It was thought that General Motors under rated the power on paper. The Turbo charger was sourced from Garrett and featured a ceramic impeller which blew the air through a intercooler to a “cermatel (ceramic/aluminum) coated pipe” which connected the intercooler to the engine.

The whole car is highly upgraded from a regular Grand National. The list of upgrades includes a reprogrammed Turbo Hydramatic 200-4R transmission, low-restriction exhaust with dual mufflers, custom torque converter, transmission cooler, and unique rear differential cover/panhard. These are just the performance upgrades. Both the interior and exterior was upgraded as well including vents located on each fender, 16 inch black mesh style wheels wrapped in VR rated tires, along with the deletion of hood and fender emblems. The interior included a dash plaque with a serial number for each car built, and a revised gauge cluster featuring Stewart-Warner analog gauges which included a boost gauge.

Back to the Craigslist car. The car pictured is listed on Craigslist in Miami Florida. This car was purchased new by the investment pool of the Miller Brewing Company employees. They felt it was a wise investment which it seems they were smart when it came to investing. For sale now for a asking price of mere $95,000. This car is believed to be the lowest mileage GNX in the world with 9.7 original miles on the odometer. This car has never been driven or even titled for that matter and still has the orignal window sticker on the window. In fact, the tires still have the factory marks and all parts on the under carriage still have the stickers from the factory on them. This car has never even had a oil change. It is the oil that was in the engine when it rolled out of the factory.

This car apparently has been started every month since it was bought and is in perfect condition. I actually saw a GNX in the General Motors Heritage Center when I was at the product and technology event. The GNX in the Heritage Center had paint that was terribly swirled and it truly made me want to cry. This is probably without question the lowest mileage GNX in the world and also probably the best condition GNX in the world as well. If you hold a conversation with any car guy you will quickly learn most have a fetish for the GNX. When the car debuted Star Wars mania was in full swing. Seeing as this car could be had in any color you would like as long as it was black, this car was nick named Darth Vader. Whomever buys this piece of history is one really lucky individual. If I won the lottery tomorrow it would be in my garage next week.

    The GNX pictured is undoubtedly a beautiful car. However, I believe that the GNX I own has the lowest documented miles at 8.4. The vehicle I own has never been detailed by the dealer — the seats are still wrapped in the original plastic. Please let me know if you would like photos — I would be interestd in any other low-mileage GNX’s still out there.

    i saw a clean 87 GN cross the block at barrett Jackson Las Vegas last year for 30k. I believe it was around 80,000 miles. 95 for this car is about right

    […] there were the low points.  One of the saddest things I saw was a GNX and, if you know me at all, you know how much love and respect I have for the GNX.  It was just this particular GNX that just made me sad all over. I was excited when I saw it […]
