2 BMW dealers I know have a few min wage Europeans washing with some kind of TFR they strips every piece of wax or sealant off the car in 30 secs they then dry the car off
On the subject of looking for a good dealer.
If you intend to keep the car, and I mean keep the car for 8-10 years then sure look after it, and search for a good dealer.
If like many on here though you intend to get rid of it, on or before the end of the PCP/lease 2-3 years, why does it matter? Life's too short to worry about swirls added to the paint randomly, or whether they will drive your car for 5 miles on a test drive after a service. Your get the GFV and more when you roll into the dealer in 2 years time when you are bored anyway. i'm sure the dealer won't care if only other dealers have washed it and it has a few swirls. The market value and GFV will dictate what its worth. They will be looking for tread depth, stone chips, the sort of things that hit the profit for the future sale.. Your not sadly passing the keys onto like minded VW enthusiasts, for them to look after your pride and joy, your dumping it at the dealer and picking up the new car and not looking back!!
So why should you care what it is treated like for such a short period of time? Unless of course you are keeping it for 10 years

I understand the pride in peoples cars but some seem to keep them such a short period of time 2-4 years i don't see the point in having high levels of OCD.
