I'm looking at purchasing a 2001 E55 with a slight vibration in the front. The car has new tires and rims so I'm assuming it's something else. Anyone know of a common problem on this year/ make that I should be concerned about?

I can deal with replacing a wheel bearing or control arm bushing.... but would really like to avoid a higher cost item.

Any insight you might have would be appreciated.
