2006 BMW 5 Series Sedan 525xi 4dr Sedan AWD (3.0L 6cyl 6M)
Nice Luxury Car (:
 We purchased our 525xi secondhand at a BMW dealership and it was certified used. The interior comfort is great, and road noise is minimal. The only thing I don't like about our 5 Series is the iDrive system. It can't be avoided (option up a standard radio like in the 3 Series), and it has radio presets, but there are no preset buttons (you have to use iDrive to get to them). The car also has an annoying "grab" in the transmission, a software issue. The performance is great. I love this car.
