EVERY buick should be restored. It's people like like bweavy and them, who just want the money for parts, instead of restoring them. It's ALWAYS worth it, trust me. There's probably less than half of our cars left because of 'parting it out' types. I'm guessing around 15,000 total IC cars left, with around 10,000 ic gn's left around. That makes them rare in my book, and they should be treated with MUCH more respect than people give them.
Guys, at this rate, it's not going to be too much longer, before there is no more donor cars. It's going to get reeeal hard to find parts for 'em, and the prices of our cars are going to skyrocket like you wouldn't believe. For all them fools who sold their factory intercoolers, turbos, injectors and wheels, for all the go-fast parts, you're going to feel like a dummy at the car show in 2028 when the all factory GN sitting next to you is commanding a 45,000 dollar price tag, ONLY because it's stock, and your pt77 turboed car only gets an onlooker every other hour. You're going to kick yourself in the pants.
Remember how mad your parents were, when they found out how much Chrysler E bodies were going for in the local auto trader? "MAN!, we used to take our challenger grocery shopping. Garage? We had no garage, we just let it sit in the rain. We sold that stupid car for 500 bucks back in 84, to buy the brand new K car." Don't be that dummy. Learn from your parents. You're driving this generations 'cuda.
