I'm in the process of getting all of the paperwork straight to buy a 2000 323Ci. Its blue, manual, and only 44,600 miles on it. The guy wants $20,500 obo but i'm going to try to get it for at least $18,000. Its fully loaded with the navigation system and all. He says the warranty just ended but is there any way I can purchase the extended one and if so do I just go to my local BMW dealership and do it or what?
