I am going this weekend to look at a procharge 2005 GTO. What are some of the key issues I should be looking for during the test drive? The owner is a friend of my father's and has been fairly open with the issues. The car has been sitting for about 10 years with only ~1,000 miles total during that time. Needs new tires, battery, and has a small coolant leak from the radiator. He says he would do $15k, but with tires and it sitting, should I try to go lower or is $15k about right with 1 owner, the procharger, and around 59k miles? Yellow wouldn't have been my first choice, especially with the black wheels, but I don't think it looks to bad in person. Has a bb gun dent in the door as well. Any insight would be super helpful.
