 I have owned this car for two and one half years and still love to drive it.  The fuel economy is great for a V8 20 city and 26 hwy (actual).  Handling is superb!  I have sports package (highly recommended) which includes wide 18 inch wheels, which I highly recommend!  Quality is top notch and fit is superior!  If you can afford it, buy the 8 cylinder as there is nothing finer than a BMW 8 cylinder.  Also the car retains more value as the 8 cylinder is in fewer numbers!
