Mark O, I really think it gets down to a personal preference between the old and the new, do you agree ? I'm very impressed with the latest GT Mustang, but still prefer to have my 51 year old Pony. Chalk and Cheese, so different ! You could spend as much restoring an old Stang as what it costs to buy a new one and that is the general friendly argument. As far as investment goes, who knows how a 2017 Mustang will be valued in years to come ? Love 'em both, for different reasons. Which one is the most FUN to drive ?
