I've had many M's and always interested in the F10 6-speed. I was able to find a low mileage example. Getting used to the car..... so far it seems a bit numb (no mods at all) but I do enjoy rowing the gears. Shifter very smooth.
Here's the car:

Also looking for a set of 20's if you have a nice set laying around.
