I do and this is what reminded me to ask this question.
My back is too bad to be able to clean the car properly anymore so I happily take it every 3 orf 4 months and have it done totally.
It comes back both looking, and smelling like a brand new car and I love it!
Currently it is like this and I dont even like to drive it and tomorrow is forecast rain, so I will not go out and get my clean car wet.
I generally have it done less often in winter when roads are wet and muddy.
