Hey guys... newbie here. I'm looking at a 1998 fairway green corvette with just under 50k miles. It is an automatic. It was originally a coupe, but was sent off to some place in florida and was converted into a hardtop convertible. Dealer has it listed at $21,000. I checked KBB and it says it should go for around $15,000. What is a fair price I can ask for, considering the rare color, and the hardtop convertible conversion? Interior is immaculate. Also, what should I look for that may be a potential thing I need to fix? Any problems I could spot on the lot or during a test drive?
