You are a gentleman ,negative thinkers are SMALL MINDS !!! It does take alot of cranking power to turn over any BMW M vehicle especially when you either disconnect a battery or don't drive often,but this guy has never even seen or heard my car and he probably does'nt even own an M ,All bmws drain battery power cause of our computers they're are always on so,, let's not entertain words with no faces every time someone is selling a car on these boards there is some clown spewing hate........Thanks.
