Sorry to hear that. I had a similar experience looking for my 08 X5.

I began my search at the local CPO BMW showroom. I saw a 4.8 they had and liked it, but it didn't have too many options. They said that's all they had. I later went home and checked on the website and there was a 08 X5 with 20k miles! I called the salesrep again and he said he wouldnt have it until monday and to come then. I did and I saw it parked very closely between two other cars. We went for a test drive and it drove great. We got back and I was looking around and saw humongous scratch marks on both sides. The carfax was clean and now the sales rep said, I already told you about this..

I told him no, you are lying, we just found the car online, how would you have been able to tell me?

Anyways, I ended up finding a private showroom (featuring lambos, ferraris, and corvettes!) and they had the X5 with EVERY single option loaded for a great price. The experience was great as well, they let me test drive the car alone; I've never had that experience in NJ before!
