2010' BMW 5 Series

I give a lot for a real buyer.
Possible exchange only for something bigger (with an addition from me)
The car is in good condition (I don't run out of money), it has always been invested in, when needed, with original parts.
The chain was changed, the turbine - (I think it is still under warranty) and many others (I have the old parts as proof)
Km is original with service book or we can check at the BMW center (not like other models year 2010 - 2013 with 200,000 - 250,000 BRED on board)
