It has ACC controls. Are these cars reliable? If I was to tackle the non-functional blower, such as replacement, how tough would that be? The 240D needs a new one and it seems like the car was built around it, the only way it is accessable is by tearing apart the dash. Is the 500SE the same way? I was able to run Carfax actually, and it came out clear. I do believe it is Euro-spec though as it seems too bare-bones for US models.
