Streetable?
A car that doesn't overheat - I hate dealing with overheaters
Pump gas. If it's a real street car, you need to be able to fill up somewhere.
Beyond that... it's all about what you're willing to live with. I run DOT slicks, no heater, no windshield wipers, and currently 4.30 gears. I love it, but it ain't for everyone.
