running the m3 at a intermediate or advanced pace can be expensive. i have figured it to be about 600 per day. 150 for gas, 150 for tire wear, 50 for pads, 250 for entry and this doesnt include all the other things like oil changes, brake fluid changes, alignment, mounting and balancing, or any of the other things we spend money on to make our experience out there good. probably more in the range of 800 per day taking into account everything. gotta love it.
