There's nothing quite like driving a convertible, especially when that convertible is a classic. Cruising with the top down and a cool breeze in your hair is one of those experiences that's bound to put a smile on your face.

He tells us he put the top down on his 1967 Dodge Dart 10 years ago, and hasn't put it back up since then.
