2003 BMW 5 Series Sedan 530i 4dr Sedan (3.0L 6cyl 5M)
BMW 530 past 60,000 miles
 The 530 corners as if it is on rails and it accelerates very quickly and smoothly.  I also own a E350 Benz and the BMW kills it in terms of performance (and the Benz is no slouch).  The difference with the Benz is that the quality of the interior is hugely superior to the 530 - indeed the 530 is pretty basic in comparison. The BIG problem with the Beemer is reliability. Since hitting about 60k it's been own thing after another.  First the door locks stopped working, then the doors started leaking, then the AC started acting up, then the alternator died, then, then.....the dollars just keep flowing out the door.  For a car that is competing in the luxury space this is just BAD
