Actually, I just bought the m3, but I had 5 e30s before. 911 SC is not the same as m3 as far as the daily driver. Porsche has very little comfort (A/C or heater) but more fun factor for short drives. It also depends on where you live, as far as climate. For example, if it snows or rains a lot, 911 fogs up inside much faster than m3... And don't forget, porsche will be at least 5-6 years older.... good luck
