 I will end up averaging about 1000 miles per month over my first year owning this car.  I live in a region with many excellent sports car roads and little severe weather.  Twisty mountain roads are the favorite hunting grounds of this predator.  Z4, CLK230 and Mustang are its favorite prey.  Although its ultimate grip around a corner may not be the king of the hill, it loves the transitions and flies through them with great balance.  Feedback to the driver is excellent.  I have the 17-inch wheels and they seem to have better comfort than the 18-inch from what I have read.  Car makes you feel like you are a much better driver than you are.  Moreover, it lets one become a better driver, too.
