Hello all, My first post here. Just got an out of warranty 740li from 2011. Have 70K miles on the car. Would you please advise 1) what are the common problems that I should look out for? 2) Is an extended warranty worth and any suggestions on who is the best around? 3) Are there any tunes for this model
I had a modded 135i earlier. Many thanks.
