What IS the BMW M3 good at?

So the BMW M3 has been out for a few months, and quite a few reviews of it are out. Time for mine! Seems like the M3 isn't good at selling. There were over 10 on BMW of Monrovia (formerly Assael BMW) and they were offering discounts for the car. Big discounts. When did this ever happen to a few month old M3 before? Answer - Never. Another flaw that is killing this car is that it has terrible mileage. It gets 14/20, and thus is charged a $1,300 gas guzzler penalty. Amazing, since the insane Nissan GT-R gets 16/21, is 4wd, heavier, and produces much more power. The M3 also isn't very good on a track, since it has trouble beating cars in its price range like the Nissan GT-R. M is supposed to stand for motorsport, and obviously it doesn't live up to its name. Therefore, the M3 must be a grand tourer? Well, not quite either since it isn't very comfortable, has terrible gas mileage, and really a 335 suits the job a lot better. BMW would have had a good case for the M3 if the 335 wasn't so damn good. Too bad the M3 is now just another car that is highly overpriced. Remember, 70k doesn't just get you a GT-R. You can also get a base Carrera, which is more desireable than a hopped up 3 series. So what does the M3 do well? Simply put... nothing much at all.
