Regarding best luxury car under $80k:
Totally disagree about the Merc win. Had a Mercedes C Class 350 CDI Blue Effeciency AMG Sport and it was nowhere as good as the F30 BMW 330d M Sport. The Merc engine rattle could wake the dead. Also, its auto box was not a patch on the BMW's 8 speeder as it always hesitated when trying to pull away from rest even after all the software updates. Then there's the handling: the BMW wipes the floor. Both cars with adaptive suspension. I could go on and on.
The C Class is an old car now and its replacement cannot come soon enough. It is perfectly ready as maggot food.
