One thing good condition of exterior is something else and original paint is something else. I assume you can understand :). There is wide differnce between price range but all depends on vehicle color (Total Original, painted or with tochups).
Make sure exterior paint should be geniune and if the car is in total original paint then you can go up to higer limit of price i.e. 650-660 Max. Thanks
Good Luck with ur purchase.
