Me to. I also put my ‘do not wash this vehicle’ hanger on the rear view mirror and specifically get the
service advisor to add a ‘do not wash’ note on their job sheet - I don’t want my car’s paintwork to get a free scratch and swirl treatment.
A 2-3 months after I bought my current car, I needed to go back to the
dealership to pick up the spare wheel (car came without one, and a factory spare was agreed as part of the deal). The salesman I dealt with when I bought the car asked me who I used to clean my car. When I told him the only person that I would let clean my car was me he jokingly asked me if I wanted a job cleaning the cars for the
dealership!
