2002 BMW 5 Series Sedan 540i 4dr Sedan (4.4L 8cyl 5A)
540i cannot be beat
 Best car I have ever driven.  Also own a CL500 and I prefer the 540 over the Merz.  Great car and the only reason I would replace is if I get a 545i.  Performance cannot be beat, great ergonomics.  BMW really builds a car around driving.  Don't get this car if you like eating or drinking in the car, that's what American cars are for.
