2000 BMW 7 Series Sedan 740iL 4dr Sedan
VERY Expensive to Maintain
 Without question, this is the greatest car I have ever driven.  Unfortunately, it is also the most expensive car on the planet to drive.  Since the car went out of warranty in Oct 2005, I've had to put nearly $20k into the car.  Something seems to fail every six months, and as someone else noted the cost of a typical repair is anywhere from $700 to $4,500.  I've had many different mechanics work on the car, and all say the same thing: Best car to drive, worst car in terms of maintenance.  Expect to put $5,000 into the car each year for repairs/maintenance.  You mat get 300k miles out of the engine, but it'll cost ya $300k to do it!  That said, the BEST ride on the road, hands down!
