i went to look at a lovely 4x4 saff today, everything about the car was perfect, the bloke took me for a run up the road and i was shocked by how well the car drove. but when we come to a roundabout as he was cornering there was a rumbling/vibration going through the car, felt a bit like when you run over rumble strip on a motorway. he said his mates escort cos does the same and he was a really sound bloke and he's owned the car for 7 years and says it has always done it. i really really want the car but i'm just a bit concerened its something serious. if it makes any difference the car is lowered on 17's with quite low profile tyres on. advice guys????????
