I have a 99 328i sports/premium package, 5 speed, black/tan. The car is awesome. However, I too have noticed the wandering feeling when driving at high speeds. I called everyone of the local DC dealers (about 5 in all) and told them about the problem. All of the service departments told me the same thing....17x8 low profile tires are going to wander a bit in the grooves on the road..put on their by narrower tires. Does anyone have this "problem" without the 17x8s?
