not happy with my new 2006 x5

I agree with the other posts that say keep the pressure on the dealer. Where I live, there are plenty of bumpy roads, pot-holes, you name it - and I don't get any noticeable creaks or other noises - 4 months into ownership. I very much doubt that your roads in NH are anything like as poor as here. If your X is making such noises, then it is just plain wrong. I'm sure 99% of X5 owners would agree. I am completely satisfied with noise levels (or lack of) from the bodywork. If you are in any way unhappy, then either they fix it or replace the vehicle. Based on my experience, if they can't fix it, you have definitive proof that it is a lemon.
