I was going to buy my son a Mustang for his Bday. Is a 2002 or a 2004 both V6 both automatics and mileage is under 130,000 and priced at $2995. Is the price fair? Which is better to own? 2004 is a convertible. Which is easier to work on and how long do they last mileage wise? Please reply so I know which one I'm going to get him. Thanks, Tanya
