The car I'm interested in is a 2001 Honda Civic Ex with 70k miles on a rebuilt engine (new clutch too). It is in great condition body-wise, no accidents, and the seller says he put in new brakes, and sparkplugs 15k miles ago. This was the seller's daughters car and its up for a really reasonable price. So...A question that came to mind is, why would a 2001 Honda need a rebuilt engine?
