How reliable is a seven-year old Mazda3?

Hi Christopher,

Yes, absolutely. Mazdas are renowned for their reliability, and the 3 is no different. In spite of sharing all its mechanical parts with the second generation Ford Focus, the 3 generally does a little better than the Ford in reliability and surveys. Perhaps the Mazda engineers do the bolts up a little tighter... Some early models apparently suffered from turbo failure on the 1.6 diesel engine but that seems to be the only thing, bar the usual history checks and damage inspection, to be worried about.
