My brother averages 100K a year on his cars, he takes a lower class for tax reasons. The two Megane-II's didn't fair well bless them, he's currently in a 57 Auris with 18K which is doing well, but rattling like a bug*er!
You will often find that most japenese cars (toyotas/nissans/mitsubishis) often have very good electrics and engines that go on for miles and miles without a problem.
But when it comes to annoying rattles - they are always a problem in them
