I have 1987 convertible mustang with 55ookm what should I ask for it

LX 4cyl or GT 8cyl engine? 5spd manual or automatic? What is the condition?

Havent driven it in 10 years? All that sitting could've caused damage by not circulating fluids and moving parts -- stagnant sitting is very bad for a car. With that said, you need to have the car looked over thoroughly by an experienced technician so he can give the car a pass or state what repairs are required. Only then can you start to establish the market value of your car. And like Tom said above, the model and equipment are very important -- a 4 cylinder automatic is crap for resale, while a 5.0 5-speed manual would be ideal.

From where are you,country? If you are from South Africa ... please let me know.

if seats are bleached , does that mean it needs a new roof and sat outside for years.......lowers the price a whole lot

Like the others said..need more information
