I have been using drive through car washes when I owned a Lincoln Navigator and never had a problem. Now I own a 2015 Lincoln MKS with low profile (20') rims and I am concerned that the car wash with its "pully rails" may scratch or damage my low rims. Anyone have an opinion or advice about this??? What type of car wash should I go to or do I have to wash the car myself?? Thanks for your opinions..
