I have an 08 E90M3 (JZB on Black) that is a year round daily driver. I use snow wheels in the winter on all the cars. I bought the cars to drive. The E90M3 has about 49k miles.
It is lightly modded with quad resonated x-pipe, underdrive pulley, K&N filter, Vishnu Procede tune with water/meth injection, H&R springs, pulled camber pins, braided steel brake lines, high temp brake fluid, and StopTech Street pads. A software update to 240E, MS intake and Megan catback are on the future mod list. It has to stay a civilized daily driver. If I had the money, I would buy a supercharger kit, but will probably have to wait a couple of years and buy a used one then.
If someone sets up an informal get-together that is not too far from me, I would be interested if I am free. I am either in Hampton NH or Concord NH.
