Don't do it sell it that is. Find another way to go to work by train or car pool split the gas cost something can be done I'm sure.
This way you still have your car for weekends and holidays, save some cash and eventually get that new one.
Another option would be to move closer to your place of work. There is always a way if there is a will
Good luck, let us know how you make out.
PS. In a few years the smaller version of our M3 might be on the market (see below like the smart car) then you can move again far away from your place of work
all joking aside ... like others said you only live once so enjoy your car you work hard and deserve it so don't you sell it hear.
