I actually had two of those '79 Pace Cars. At the same time. And I was working for GM at the time. I was looking for a 5.0L V8 model but couldn't find one, so I bought a 2.3L turbo. Had it for a few months and a 5.0L appeared out of nowhere, so I bought it, too. The 4-cylinder turbo had the full decal set applied, the 5.0 had the door decals still in the box.
One day I'm driving the 2.3T around downtown Flint, Michigan, sunroof open, windows down and people are blowing their horns and waving at me. Narcissist that I am I wave back and think "yeah, I know...cool car...thanks". Pull up to a stoplight about a block from my apartment and smoke starts rolling up my windshield. Luckily, I was across the street from a fire station, so I pulled into the drug store parking lot and holler over to them. Then I did one of the stupidest things I've ever done in my life. I opened the hood. WHOOOOSH!!!! Slammed it and let the firemen take over.
Insurance replaced the engine and completely repainted the car, including installing the decal kit. Wound up giving that car to my brother and hung on to the 5.0 until I got my first Fiero.
