Well ive had my 172 for 2 weeks and with in the first few hours of driving it, it developed a rattle from the passenger seat, not just a little rattle but a clanking. Anyway i took it back to the dealer today and was told " they are supposed to rattle when noone sits in the seat" what a load of b****cks. Anyway i had a 1.2 before and the seats were exactly the same and they didnt rattle. Does anyone know what parts are needed to stop the rattling, i think the seat is ratteling on the runners. Help the rattle is driving me nuts even with the stereo up loud i can still here it.
