yeah it depends on year, mileage, title status, condition, and overall fit and finish
example would be one for sale here in the bay area going for 13,800 obo
its a 01 NBP ITR w/65k miles clean title stock
say it has 165K miles, that would signifigantly drop the retail value a little more
i'd check KBB or edmunds for a more generalized price range
good luck
