I have a 2015 Silverado ( Rainforest Green) that I ran through a locally owned car wash with about 6 places for over 5 years. It was sold to a nation wide Corp. They changed all the equipment and rid themselves of most employees. For those 5 years not much as far as scratches go. Once the new equipment went in it was all down hill . I took it back after a half dozen washes with heavy scratches. They accused me of taking it off road. Never will I go though one with the new Tahoe. Toucheless during the winter but will wash at home for now on. They did take care of a minor buff job. Wheel wells down. Beware !!!!!
