Fun is the car's only purpose.

The budget is about $30k. I already have a family hauler, and an efficient commuter. I'm not an engine rebuilder, but a head gasket or a timing belt is child's play, and wire repair is my happy place. What have you guys driven that made you grin every time you got in it? What have I left off the list? Has to be hard-top, RWD or AWD, with a manual transmission.
