So nearly all of the automated car washes in my neck of the woods are pushing unlimited monthly wash subscriptions----ie, raising the price of an individual wash so that a monthly plan is cheaper so long as you wash your car >=3x a month.
Being that it's salt season, I signed up and wash 2x/week, but going back to the touch-free washes once the salt stops.
Would you take it? How often do you wash your car at drive-thrus?
With my old Honda that I drove to 180,000 miles, I rarely used a brushed, drive-thru was and I had rust issues in the exhaust system at year 14. My parents were religious about washing their cars (automated, brushed washes) in the winter and they didn't have any rust issues w/their Honda even with 290,000 miles.
