2001 BMW 5 Series 540i 4dr Sport Wagon (4.4L 8cyl 5A)
I bought this car for my wife as a car to drive around kids in - I think I want it for myself! This car has got all the power you will need, excellent handling and it's smooth as silk. The 540, like the other posters say, is well worth it over the 528. There are too many great things about this car to list... simply love it, love it, love it.
Build quality, tight lines and power. The fold down seats are a definite plus.
