One interesting tidbit about this car is that one of the Goodyear tires had backwards lettering-indicating that it was an experimental tire that was not for sale. In the course of freshening No. 001 up, GM had to find and purchase a complete, brand-new set of wheels and tires for it.
Very little had to be done to No. 001 to turn it into the better-than-showroom stunner you see here. A few dents have been pulled over the years, and though our source thinks that it wears a factory paintjob-polished to this show-quality shine with "lots of show preps"-he concedes that it's possible that because it was the first GNX, and a PR car, GM could have given it a special paint job, though this cannot be confirmed.
Mechanically, the only problems have been a minor brake leak or two and a couple of loose driveshaft bolts-easy fixes for the numerous, talented GM employees that are tasked with lavishing TLC on No. 001, along with all of the other priceless works of GM art stored in a secret building in the northern Detroit suburbs. Though it does make it to large national shows like the GS Nationals, and the occasional local show like the Woodward Dream Cruise, No. 001 passes the time with monthly maintenance checks and a yearly full maintenance where approximately 10-15 miles are put on it. But after spending some time with it, I can personally attest that even 21 years later, this GNX is ready, willing, and able to whip up on most of the rides on the road today. It's a true legend.

 The GNX got way bigger Goodyear...  The GNX got way bigger Goodyear tires than regular Turbo Regals: 245/50/16 in the front, 255/50/16 in the rear, with different-offset 16-inch rims. The fender flares and vents were unique to this model as well. Did all TRs get paint this nice? Negative. |  The key to the GNX's awesome...  The key to the GNX's awesome straight-line performance was the torque arm suspension. In concert with a Panhard bar, this setup actually made the X's body lift up in the back while brake boosting, digging the Goodyears into the ground and allowing for an impressive blastoff when the brake was released. The machined GNX cover was a nice touch-and as the lower torque arm mount, a functional one as well. |  Think it was easy channeling...  Think it was easy channeling massive amounts of turbocharged Buick torque through this chassis? The engineers knew better: besides one or two custom moonroof GNXs for ASC executives, all of the GNXs were hardtops, and special trunk braces and body bushings-along with the front torque arm mount brace-kept them from twisting like pretzels. |
