That does not sound right. 535 base MSRP was more than that, iirc. And 2011MSport was a $6500 package.
Have a local BMW dealer provide you with the build (really suspect this is not one) so you can understand what I really in he car. Also, what is build date? Check the placard on the door. Do not buy anything earlier than 2/2011 build.
Spend some time searching here. Educate yourself as to the car. This deal sounds fishy.
