That was the GNX that Heath Elmer modded.It was in Popular Hotrodding in early 05 and then it was on Ebay shortly after.I copied the picture and the description from the auction.

I have no idea where the car ended up but it is awesome.
Here is the ebay listing:

1987 Buick GNX w/24k documented miles, 059 of 547 produced. This is one of the nicest GNX's your ever going to see. Read and view the following information and you will certainly agree! Im not going to explain GNX history because if your looking for one you already know its one of the coolest cars on the planet! This car has just undergone a 6 month restoration and has only test miles on it. It was just feature photographed for a July 05 car magazine and I will only disclose which one to the new owner so don't ask.
First a quick introduction. My name is Heath Elmer, I own and built this car. I've built several high end Buicks, Porsches and other race and show cars that have been featured in magazines and shows over the years. To make this short, I build extremely nice cars. I use the best parts available in all of my projects and I build my cars to drive, race, show & win.

Paint. IT HAS NEVER BEEN IN AN ACCIDENT, NO STORIES HERE! It had some minor door dings and chips in the orig paint and I'm very picky. I went to great lengths so that the paint was better than new. It was dis-assembled prior to paint. I also removed the nasty looking rock guard and straightened the door bottoms and rockers. GM put this crap on to cover up how bad these cars looked on the bottom. The paint job was professionally done in base/clear. I've built 11 Turbo Regals and a TTA, I know what I'm doing and how they go back together. The paint job cost me $5000. and I did all the R & R. I have pictures of it before it was painted and while it was apart that go with the car.
The bumpers have been smoothed (I removed the bump strip and guards) for a cleaner look, I dislike the stock trim on the bumpers and its easier to clean without it. THIS CAR HAS NEVER BEEN CRASHED. Stock ones are easily found if you choose to change them back. They are not specific to a GNX. The original aluminum inserts are still there. Included in the sale are the bumper parts I removed. You could drill the holes back in them and put the trim back on easily.
Interior is 100% stock and 99% flawless, no spots or stains, never smoked in, the clear wrappers are still on the dash pieces. It has new floor mats and a 9 piece trunk kit. I changed the boost gauge in the dash to an Autometer that had a 30lb boost reading. I do have the guage I took out. The 1% is the plastic dash top has a 1/4" crack on each side by the speakers (they all crack and new ones are available for about 100 bucks) Also theres a new Scanmaster 2.1 tuning tool.
Exhaust is upgraded from 2 1/4" to 2 1/2". Its mandrel bent aluminized duals with ATR stainless steel mufflers and a Terry Houston 3" dp. The headers and DP have been HPC coated. This stuff was over $1000.
The Engine. Why was the engine opened up? It popped a head gasket and had a leaky freeze plug in the back of the block from sitting in storage and since it was out of the car we changed the cam, ported the heads & intake, re-ringed it and put new bearings in it. The engine was professionally done by Joe Martin Racing Engines in Tempe, Arizona his # is 602 451 5776

I have a friend who has a GNX turbo but it would have to be purchased through him, it would not be included with this car. I've described it the best I can, if you have a question please ask.
This is the nicest Pro Tour GNX on the planet. If you've been waiting for the right car here it is. Only 547 of these cars were ever built and only in 1987. It looks, runs and drives better than you can even imagine. I can email more pictures if you want to see something just let me know. It is available for viewing any time and I do reserve the right to end the auction early.
"Be one of the fortunate 547"
