and I would say that 13,500 is a good price as well. sounds like your car has a good history, is well documented and is in good shape so those are all considerations for pricing a car out. it seams like once a 300zx goes below the 60k mile mark prices start going up. i saw a guy on ebay with a 40k mile TT and he was asking 24g. a SMZ with under 10k miles was going for only 6g more.
27k original miles on my baby, if my girlfriend only knew that I think about it more than her...
