Why I ask is because I just had an interesting conversation with a detailer who will be doing my S when I get it. His suggestion is to speak with the sales and insist they DO NOT prep the vehicle. Just leave the protective wrap it is shipped with on the car. He had a MB and Volvo - both new in his shop and he showed where the dealer prep makes his job harder. Looking closely you can see swirls on the paint from the dealer prep. He has done several Tesla's and noted they are no better. I'm sure they are trying to do the right thing when delivering a new car but the detailer is not a professional in that field. He sometimes spends a day and a half (his words) correcting the job dealers have done. Whether it's removing chemicals, swirls or light scratches (I could not see them myself) I will be paying more. Anyone pick up their car with the wrap still on?
