Worst car I've ever owned. Beautiful looking but leaves you stranded.
 The only thing this car has going for it is looks. The car is a worthless piece of crap in my opinion. I bought it with 70,000 miles and a month later, the car died. It needed a new battery and had $3,000 worth of oil leaks. My mechanic told me the oil leaks are standard maintenance on this BMW. A week later the car wouldn't start again & threw a check engine light. It needed a new thermostat, coolant, and MAF sensor. Two weeks later I discovered another oil leak at the oil pressure sensor! This is ridiculous. I've owned a 2006 Toyota from 0 miles all the way to 140,000+ miles and it never needed a new battery, never had oil leaks, never a check engine light, and it never left me stranded.
