I have only had experience with the West Palm Service center. Although not always perfect they work hard to get it right, provide real time updates, are always super friendly, and I've been provided Tesla loaners nearly every time I have required service. They have even done work under warranty when I thought it should be something I pay for. I have even sent the entire service dept pizzas for lunch on one occasion for how helpful they were.
Since you had your car wrapped and ceramic coated I am surprised you even want them to wash your car. I've never seen a car dealer wash that was done properly. I actually leave a note on my service record and place a sticky note inside the car instructing to NOT wash my car. I only allow them to do an interior clean. Dirty water, dirty wash mittens or brushes, coarse and dirty drying towels, cheap soap..... I could go on and on... If you want fine scratches and swirls everywhere let them go for it. But if you want you car mirror finish status then tell them to stay away.
My car was returned filthy in a much dirtier condition then when I took it in. There was a layer of dirt on it like when people write “wash me” on a car... and the X parts in the back seats. It was at the service center ——>body shop—-> service center for 8 days to fix a little ding that normally takes a day, an hour, at most if I took it to a regular body shop.
It is a brand new 150k car. The level of service is really very bad.
