I commute 50 miles a day in my M3. It may not get the best gas mileage but it is fun to drive. I drove my Porsche to work every day too when I had it. Not sure why you come to an M3 forum to ask people to talk you out of buying an M3. The 335i is not an M3. Not even close. Why does he want something rare? They don't make rare special edition commuter cars. Those are called Buicks, Fords, C300, 328i, etc. Go get a 4matic C300 and call it a day.
