DuoWing, to give you a clear idea of exactly how my car was when I bought it, here are pictures of the day I got my car. I was very lucky since I only looked at about three other Z's before see'ing this one. As you can see the bumper was also damaged, I had that repaired and rechromed as well.
Only advice I can give is to be patient. One of the major flaws on my car is the electrical system. Practically nothing worked, and a couple days ago my ignition stopped giving spark, and now I have to fix that too. Whenever you truly consider buying a car, you know deep down whether or not if it's the right choice. Just be logical. On my car everything appears to be great, but man o man was the suspension, brakes, and electrical system neglected. Everything was so shot it was ridiculous, and to get everything up to my standards has been costing well over double, close to triple of what I was expecting to spend other than the price of the car. I'm lucky I make as much money as I do for being 17, otherwise I simply wouldn't be able to afford to keep building this car.
