Hey guys, wanted to get your incite on a 09 535xi with 45k miles. Car has great history report and seems like its been over serviced with its oil changes and inspections. I was wandering is this a good year and model to go for? Ive hear many people having issues with the 4wd system. Wanted to see if that was on the earlier models or do they all have issues. Also they are asking $14k for the car. Thank you all in-advance. By the way its got cold weather package and M-package.
