Though I had heard of Smart Cars, I recently was informed to the fact that they are highly customizable. Tuning kits available from Carlsson Products allow you to change rather significantly the look of your Smart Car. The kits include alloy wheels, an aluminum pedal set, a fog light, front spoiler, grill inlet, handbrake lever, rear skirt, sport rear silencer, and wiring harness.
Never satisfied with the status quo, though, others have come up with body kits that totally change the look of the Smart Car. Here's what they've come up with so far.
