I bought my X3 of a 3 year lease - dealer gave a certifed warranty until 50k miles. Mine has a the 6 speed manual trans w/3 litre engine many options (moonroof and MP3,etc)
It drives great, but the orig sticker was about 45,000 and I paid much less.
Maintenance on this car is exppensive - to replace one tire was $280 and BMW recommends only oil changes after 15,000 miles - much too long.
It's a fun car to drive, habdles great and has some storage, but I do need lots of seats.
