Did you try Openroad BMW on route 1. I got a decent deal from them but i could have done better.... but i was ignorant and did not know of x5world then. Since you are more informed you have a better chance of getting a steal

Good luck... and the key is be patient.... and dont be implusive when making a decision. This was my first X5 after driving camry for 5 years and my suggestion is test drive a few X5's (both new and preowned) before finalizing a deal so you get the feeling of German cars and not be impulsive when making the deal.
