2007 BMW 5 Series Sedan 530i 4dr Sedan (3.0L 6cyl 6M)
New to BMW
 After much research I made the plunge and bought a low mileage 530i.  My observations:  Ride: the car has a great tight ride.  Either you like it or you don't - I love it.  iDrive: reviews of idrive nearly caused me to buy another car.  If you expect to get in and drive off and immediately operate idrive, you will likely be frustrated.  If you will read the manual while sitting in your driveway for 20 minutes, it is not much different than Windows and a mouse.  I'm 57 and computer literate.  Climate control was the only part of idrive I did not master (without needing to look) in 24 hours.  Fuel economy from FL to GA was an amazing 31 mpg @ 75-80 mph. I love the car.
