What, you mean like, busted mirrors ,broken antennas,torn off molding,missing wiper blades, scratched paint, stuff missing from inside, spots that are'nt clean and an un-attached un-caring person who's in charge! naw....never!
Not a van but I ran my wife's Jeep through one of those new Laser washes . I was really impressed . It didn't miss a spot - even got between the spare tire and the tailgate . This one was next to a WalMart and the wash option was on the WalMart diesel pump ,
I installed them for awhile - the whole secret to touch-free washes is the soap and temp of water. A dual pass pre soak is the best. Now as long as the wash is maintained you shouldn't get any damage to your van.
