The sheer number of them (audio, nav, voice commands, HID, back-up camera, cooled seat, etc.).
The price is incrediby low given the numerous standard features and the quality of both exterior and interior appointments.
No discomfort noted on several trips of 250+ miles. Adjustable lumbar support is very nice (not just in/out, but also up/down).
After six years in a sport pkg-equipped 530i, the Genesis ride treats my 51-year-old bones very nicely.
