im thinking of buying a mazda 3 and done some research and from what ive read its seems to be a great car! i was just wondering how many miles the engine will last and its over all life span. Has anyone ever had any problems with this car? Its a 2008 mazda 3 (im not sure yet about the i,s, or grand touring) but all the ones im finding have about 40,00 miles and are about 10k is this a good deal?
