May have to sell my Stang and I would appreciate any help you can give me on determining a fair asking price.

97 Mustang GT Vert - 36,000 miles Good Condition. Auto. New stickers, synthetic oil, accessory belt. Intake manifold replaced a little over a year ago by the dealer. No mods besides K&N intake, I also replaced the headlights. The car is clean and in good shape, it is stored in the garage except when driven. Thank you in advance for your help.
