Some people are telling me to wait and not get a used P85 plus and wait for a used, standard 85D because it should be the same price. I want autopilot especially if I'm paying $85k ballpark. The two models have the same speed and I'm guessing AWD will be better than the plus. I went to the Ev-cpo website and noticed a few used P85D but no 85D. Why is that? People don't want to give up their 85D?
