I believe most customers buy the top wash for the full service option since it includes vacuuming, interior cleaning, and towel drying. Not too sure if that goes the same for the ride thru exterior option.
I kinda hate the fact that the indoor HVAC system and all the pipes are exposed to the car wash's conditions. If you look near the rinse arches, the HVAC system is on the side where the lobby hall would be.
