Im unsure if its worth 8 grand but its one nice ride. i mean i could never come up with that money so i alawys buy cars that need more work.But ive seen worse cars go for around the same price. Maybe a few people on here could tell you a better figure on how much its worth, but i dont think youll regret getting it even if it is 8 G's.
Also, the mechanic might point out some flaws and then you have a good case to lower the price.
Good luck.
