Ive just bought a mazda 6 wagon,2006 and the car has 130 thousand miles,Im wondering if there are any problems that are common to these cars particuly front end as its got new brakes ,exhaust,I have to pass a safety check to get it on the road so if I can get a heads up as to what they usually need it would be helpful. It deives well and straight but it does seem to thump a little when you go over big bumps.It may be nothing and I'm going to check it myself but it never hurts to know where the problems occur most often. THANKS DAVE S
