2007 BMW 5 Series 530xi 4dr Sedan AWD (3.0L 6cyl 6M)
There is much to like about this car. Performance, styling, and reliability. It also seems to maintain value. There are some frustrating features on the car - the iDrive takes some getting used to. Something that should be simple, like tuning the radio, switching from CD to radio, even the climate control, has been (in my opinion) over-engineered. Often multiple steps are required to perform a function that could be more easily done with the turn of a knob. The sun roof is very noisy (after the sale, the rep. said all 5-Series have excessive wind noise when closed). I usually just keep the interior cover closed to avoid the noise. Interior cabin storage is non-existent, but the trunk is large.
Styling. Performance. Xenon headlights.
Eliminate the wind noise from the sunroof. Simplify the controls.
