2007 BMW 3 Series Sedan 328xi 4dr Sedan AWD (3.0L 6cyl 6M)
CPO 3 Series 
 Bought this car with 35k on it in November of '09. It was CPO'ed and I really believe that is the way to go. So far, the reliability has been great, as I drive 110 miles round trip to work everyday. This is my first bimmer with many, many more to come.
