It is not the right machine for this use.

I only do this 8 mile commute once a month now. I do a 10 mile drive to my in laws and then back again once a week. The rest is just short journeys around town. I would probably go for a spirited drive once a month in the countryside pushing the car.
They say that diesels should also not be used for short journeys but I've had an E46 320D, F30 320D and 330D over the past 15 years with no engine issues.
Is using an M3 in this way more risky than a diesel?
