I bought my first Mustang, a 68 fastback, I'm a bigger guy 6'5" 350, so the car is kind of small for me so I'm thinking about selling it, but don't know what direction to go to get top dollar for it, it is a complete car with a 289, made in California sold in Seattle, the guy I bought it from said he parked it in 1990 and it sat in that spot until I bought it, body is in good condition, minimal amount of rust, interior is complete with console, PLEASE HELP....
