Hi Slybry,
The are other gas stations that offer the "soft cloth" wash. So, they do not use brushes. Just a long strip of cloth that does make contact to your car. I know a few people I've spoken to personally say that method is the only way to get a "clean" wash, well other than handwashing it yourself.
But I will go for the touchless first. If that doesn't work, then I will try and find a place that will do the exterior wash and wax for me. I might get the interior done as well. I had the both done last year. The interior is still very clean, but the vents are dirty from all the dust when I had my car painted.
