If I hadn't convinced him to check out the GN that fateful day, I know I wouldn't presently own this car. I feel blessed to have been a part of the car's history and extremely fortunate to own one in this good condition.Needless to say, after my dad's test-drive with a burgundy Regal Turbo T (the salesman couldn't find the keys for the GN on the lot for some reason), he was signing the pink slips on the GN! That was my first experience of buying a new car at a dealership, too...I was all of 17 or 18, I was in disbelief that me dragging my dad to this car lot on the other side of town resulted in him buying the car on the spot!
The GN has a lot of history...I got to drive it to my grad, a number of weddings, my younger brother drove it for his grad...when the parents were out of town, we'd sneak out and drive it and make mischief, and blow the doors off of Corvettes, embarrassed well-to-do preppies (this was the late 80's, haha!) in their shiny red Camaros, wasted tons of 5.0L Mustangs, had a number of Porsche drivers puss out at stoplights...and eventually my dad caught me after recording the mileage.
Fast-forward to today. About 7 years ago, I bought it from my dad with I believe about 74K kilometers on the odometer. He took extremely good care of the car, never winter-drove it, frequent maintenance & engine shampoos...I knew what I was getting for the family-friendly price of $10,000 CDN.
The main problem is, in the last several years before I bought it, my father had driven it like an old man, and the GN certainly wasn't meant to putter around...so by now, although it still runs great, it's rather sluggish right off the line compared to how I remembered it. It still has stupid mid-range power though. 
My dad originally purchased the car with Centerline clone wheels (another suggestion of mine; 15 x 7" with stock P215-65-15 tires)...the original GN wheels hardly saw the road other than the drive from the freight truck to the dealership. (I still have the OEM wheels & center-caps, they're in near-mint condition.) My dad also had a wing installed on the day he bought it; one of the salespeople recommended it, I believe it's a Fiero wing. It actually fits and looks great, and certainly sets the car apart from all the other GN's (not that there's many around these days).
Since I bought the car, I bought new, genuine Centerline Auto Drag wheels, 15 x 7" in the front, and 15 x 8.5" on the rear with wider P235-60-15 tires to properly fill out the wheel-wells. I always thought the 15 x 7"/215's in the rear were sucked in too far and didn't look aggressive enough. I also added variable-rate springs in the back to stiffen up the rear suspension.
Pictures of how it looks these days...
The problem was ignorance. The GNs had a different brake system than the Hydroboost system that's like every other vacuum-operated brake system you see on GM cars. The Powermaster system only appeared for a few years on the GNs/Turbo T's and operates differently. It's fickle but once you know how it's supposed to work, it's actually quite easy to troubleshoot. The problem was we were overfilling the cylinder reservoirs. 
The fender-side one should be about 75% full when cold, and the engine-side is only about 25% full. When you turn the car on, the reservoirs should normally fill up to the correct levels. So once I turkey-basted out the extra fluid and drove around a while, everything sorted itself out.
I read about many people doing an F-body ('82 - '92 Camaro) radiator swap, those can be had for under $150 but require an external oil cooler to be installed, and a fair bit of modding to re-route & connect the tranny cooler lines. Since that would save me about $300 after all was said & done, that's what I decided to do.
As with my RC builds, I'm never one to just leave well enough alone.
