toyota corolla or honda civic because it can be afforded by almost anyone, a good gas saver, great daily driver, very reliable cars. just my
but if we are talking exotics here...id go for either the ferrari enzo, maclaren f1 or porsche carrera gt. the reasons are self explanatory.
***edit*** ow can i add on the hybrid vehicles too. honda civic hybrid and honda insight, and the toyota prius.
