Anyone give me a value on an 86ttop for sale

[85ttopsbob]

1986 ford mustang
fuel: gas
title status: clean
transmission: manual
5.0 , 5spd T-top car 86,000 orig miles all stock motor unmolested just tasteful upgrades full exhaust, Hurst shifter and 3.55 gears. Pony wheels, has air conditioning . Great driver . Will take $5000 cash before Christmas

Does puff some smoke under full throttle , valve seals dried out prob and trans needs to be warmed up a few minutes before heading out , 3rd syncro is weak.
That's what I'm told
any ideas on a good value
Thanks guys
