This is a tough one. I get it that it has so many memories for you. I enjoyed reading the back story as well. Part of me wants to see it restored with new parts especially the chrome items. Another part of me wants to see it merely cleaned up and left as is because as others have stated, it's original only once. That aside, I'd leave it as it is and continue to preserve it as long as possible.
Excellent build. Like others have said, this is my favorite year for Trans Ams and this is an easy kit to build and detail. And yours is very nicely done.
Very cool build. Gunmetal and red looks great, like the body striping too, very nice shine and excellent wheel, tire and brake choice. The Galaxie is every bit as cool.
Mica Blue and silver stripes look great on this build. I agree about the wheels, they look good on this car, gives it an even more muscular look. Good job.
