"I owned 2009 750 LI bought it brand new from showroom floor, I had bad experience, we just kept coming back to dealership without any answer what is going on with the car.everytime we bring the car back to dealearship,they just told me there was a code in the system and they just clear the code. the engine keep shaking everytime we stopped in the traffic or made full stop. we were in branson,MO once and caught on traffic and the engine shaking and almost shut dowm in the middle of the hill. I have 3 years old girl sitting at the back seat and we just thankful because of the traffic or otherwise somebody might hit us from the back. we called BMW dealer and told them what happened,and they told us to bring the car in.we took the car to the dealer but they said they did not find anything wrong with the car again they said there is a code in the computer and they just reset the code. it is not worth it to buy almost $100k car but have a lot of problem that they can not find what is wrong with it. we really dissapointed.......till we trade the car with MB. AS far as the design and the comfort we do like it but, it is just a waste of time if everytime we need to go back and forward to the dealership and they do not know how to fix it"
