I have a young family so the Lexus is alot easier on fuel,tyres and everything in between.. The m3 is a great car you do not need to explain what it is everyone knows what it is and what it is about I have a business so it looks bad with the m, the Lexus however it is a sleeper those in the no no and and can't get enough. I would only change for another. It is faster than the m in a drag but not on the bends. I think the 2012 with the better springs and LSD would be great. Mine is 09 I have the black dash but no LSD
