Hi all. New to the forum. My step daughter has just got a 2004 Cooper bought by her dad. He's not much of a car guy or petrol head and has bought one with 89k miles and no service history at all. I've discovered that we get a vibration and rumbling noise once we go over 65mph. You can feel it through the steering wheel and the floor if you sit in the passenger seat. It's worse under exceleration and lessens when you come off the accelerator. Also had a similar vibration going around a round a bout. Under 65mph it doesn't do it at all even if you floor it. I thought wheel balance or buckle initially but as it goes away when you come off the accelerator it must be something else. It seems perfect driving around town. No noises at all. Any ideas what this could be? The second hand dealer he bought it from has given a 3 month warranty so it will be going back to get sorted, just would like to know what this could be in case it could be a sign of further issues to come. Thanks, Chris
