2001 BMW 5 Series Sedan 540i 4dr Sedan (4.4L 8cyl 6M)
CarMax LEMON
 Bought the car from CarMax. It had obviously not had any kind of presale inspection cause when I brought it home, oil leaked about 40 yards across my street from my engine!!  Within the first year of buying the car, most of the engine needed replacing, the transmission had to be replaced and much of the suspension.  And, at the time, it only had 70K miles on it!,  once repaired, the care was awesome to drive and the performance was great.  At 130,000 I had to replace the engine. At 147K miles, the car was in an accident and declared a total loss.  Because of the cars age, the value is only $4,200.
