I own both a 2010 3 series m with an auto and a 2012 v with sedan with an auto . The v is way more car as far as interior the BMW interior is more like a vw . The BMW is a better handling car I know all about the v beating the 3 series but its because of the horsepower . The BMW is and will be better for auto cross if your into that . Because of the balance. and you can toss it and it will go where your looking . The V is just way nose heavy and on the short tight turns you better own stock in a tire company . The V is just as good on the longer fast turns maybe even better . As far as power the V is great stock I changed the pulley and added a second inter cooler with a air intake it's an animal now on the road course with the traction control off it looks like a drifting contest .way fun but your gonna pay for the rubber it will wipe out . Given a choice I drive the V my wife drives the M . The V at the drag strip is way big fun it smokes Shelby's Vetts challengers amg 63 and the list goes on and that is with the stock ps2 tires . If I could afford it I would own a 911 turbo S it costs as much as a small house . And about as much to maintain as the space shuttle . That's my 2 cents any way . The V is my choice even over a Vette or a exotic car . It does it all and does it all well .
