Hello,
It's hard to give you a precise evaluation without seeing the car, it's probably around $8,500 - $10,000, it's depend of a lot of thing, is the paint is OK ?, the top need to be redone ? brake and tire ? did you have some recent bills of repairs or new parts ?
I found one whit 57,000 miles on Ebay : 170113282185, the owner ask $8,500.00, it's an hard top, so your car got a better value.
