You will never know what they do to the car during this one year
period.....like hard driving, worn brake pads, faulty electronics
on and off and etc so best is to send the Mazda to STA for
inspection and only commit if the result is A or AA (cant remember)
and no issues with chassis, wheel alignment (if out there seems
sign of collison) and engine mounts.
But i think new Kia Forte is a better buy as now they give 5
year warranty so they are pretty much confident their parts can
hold up well....but for used car hmmm not too sure..
