i have a brand new mini. i am currently driving 10 miles to work, so it gets nice and warmed up. but... i might get a new job that is 2 miles away. it getting super cold here in cleveland and there is no other way to get to the job but drive or walk in sub zero temps. and i'm not walking. so if i drive my mini in the morning 2 miles to work there is no way it will be warm all the way. is this really bad for the engine, and if so what am i supposed to do about it. help!
