2002 BMW M5 Sedan 4dr Sedan (4.9L 8cyl 6M)
The Real 4 Door Sports Car
 I bought it because there really is nothing else in its class.  If you want a very fast and very comfortable big sedan with a 6 speed, this is your only choice.  I owned an M3 before, and the M5 is much more comfortable/luxurious.  The M5 does give up quite a bit of agility to the M3, but it makes up for that with the quiet and comfortable ride.  Have a very thorough pre-purchase inspection done as there are some very expensive parts on this car.  Look for a well-maintained car that was owned by an enthusiast. Reliability is very good for a car in this class, but you will be in for a surprise if you are not used to BMW maintenance/repair costs. They need all cooling parts replaced @ 5 years.
