$4,000 · 2006 Smart Fortwo

One owner. No accidents. Has been regularly serviced and well maintained. Great fuel economy, parking is a breeze, and the diesel engine is practically bullet proof. Can be driven in fully automatic mode, or a modified manual mode where you shift gears but don't have to worry about a clutch. Makes it really fun to drive. Everything is in great shape, the only exception being the AC which is currently not working (but could be remedied) and this is reflected in the low asking price.
