If you were driving a base model 528i then people think that you are driving a $70K car, to most people M3 is nothing but a 3 series, which is pretty much basic German transportation.
I remember a similar conversation when i bought my M3 and the persons reaction was.....wow, you can get a 5 series for that price
Overall, who cares.
