I am looking to buy X5 4.8 and I understand the 08's are starting to come into the dealerships. The local dealership have several 07 4.8s and I like one of the them, which is completely loaded. List around 78,800.

Right off the bat the sales offered 2700 off. What do you guys think? I never bought X5 before and I don't know how many % off is a good deal.... Thanks for any help.
