This tiny Shelby Cobra 427 exudes big style despite its diminutive size. Rather than a big block V8, this one only has a 100-cc, single cylinder. The side-exit exhaust is fully functional, though. In an interesting touch, the eyes in the Cobras on the seats have LED lights in them. 

RM Sotheby's estimates the Cobra to sell for $10,000 to $15,000.
