Unsatisfied 
2001 BMW 5 Series Sedan 530i 4dr Sedan (3.0L 6cyl 5M)
Numerous Mechanical issues
 I have heard that these cars were very reliable. Mine was extremely fun to drive, but had numerous mechanical issues. Maybe I just got a bad one. Had to replace the drive shaft in the first year, drive belt tensioner "exploded" causing loss of power steering and cut hose resulted in overheat. Right front suspension replacement required before 50k miles... not driven very hard, numerous other issues final stage unit caused air conditioning to fail, replaced twice during time I owned, etc.
