I have placed a deposit on an S85 and have a few days before confirming. This morning I am seriously thinking of changing the order to the AWD (two motor) D version ($4k difference in price). When I placed my deposit last week some of the Tesla service guys voiced that it was a great time to buy a Tesla as many of the kinks have been worked out of the S as a function of the number of years that it has been on the street for refinements and improvements. I am a bit concerned about being the early adopter on the new All Wheel Drive version and the associated drive train. Any reactions, thoughts or perspectives would be appreciated.
