1966 Mustang

Found a 1966 Mustang with original motor (mileage unknown), new
transmission, speed shifter, headers, twin 2.5 inch pipes,1969 front seats,
new upholstery, no exposure to salted roads or coastal salts. That's all I
know about it at the moment. Assuming my mechanic says it's mechanically
solid, what's it worth; they're asking $9500.
