Fox Body Mustang
Sure, you can go out and buy a brand new 2015 Mustang. Or, you can pick up a dusty old Fox Body, take it to the garage, and shove as much power as you want in it.
It may not be the manliest of manly cars, but the old-school Miatas are some of the most fun-driving, easy to work on cars around. Perfect for a track day, or just some open-top fun on the highway.
Maybe something riding high is more your style. Like Mustangs, the old Broncos are great fun to work on with you and dad. And if you do it right, they come out looking pretty clean, too.
Any Old Chevy
Really, anything with a Chevy badge and a V8 should be the perfect formula for some father-son bonding time. Chevelle, Corvette, El Camino— you name it.
