 Bought my 2013 M37 sport 5 months ago and have no regrets. The M37 has been recommended by Consumer Reports for the past 3 years as their top luxury car. I looked at the E350, Lexus GS sport and the BMW 5 series but bought the M37 based on it's performance (0-60 in 5 sec), beauty (looks like a Maserati-Jag hybrid w/muscle) and solid reliability (due to it's low repair cost it's recommended as a used car). My car is quick and snarls (I love it) when I speed up to pass someone and I have caught a number of BMW boys giving my M37S a second glance..... You gotta check this car out. You will love it.
