BMW and safe driving
 BMW has a good look and performance but everything else are poor. I drive this car a year and i am not impressed. The major problem is with service and wheels and run-flat tires. The aluminum wheels keep cracking in normal driving conditions, and suddenly your tires can lost all air in higher speed driving. My car has 20K miles and had to replace all tires and two rear wheels. It is costly but BMW denies to take the blame. This is a bad design and BMW blaming owners of bad driving, while it is due to very stiff tires which transmit vibrations to the rims which cracks. On top they dont have tires to replace and you need to wait a week, while driving a junk car.I don't recommend BMW at all.
