I owned this car for litte over 2 years, and only 6500 miles. 42 days in the shop!!! That's about 2 days for every tank of gas. This car (and many other BMW's) has the 405 hp N63 engine. Many comments on the net say that this thing is an incinerator on wheels. Yes, it does run extremely hot. BMW knows this and has underway an extensive service campaign, where they are replacing many major engine components. They have also shortened the service period by half, from 2 years to one year. My problems and issues with this car are too long to list here. Bit I would NEVER, EVER buy another BMW.
