It seems to be a combination of Hanna Car Wash and Sherman equipment before their fusion to Hanna-Sherman in 1993 (or it's actually an early Hanna-Sherman tunnel). The frame construction, tire washers and second mitter (HSS-2) are Hanna while the first Mitter (Dynamitter) and illuminated tubes at the rainbow foaming wax station are Sherman. The side washers, rockers and Foam Wax Applicator (Tripple Foam/Polish Applicator) are maybe Hanna as well. The dryers are Proto-Vest.
Depends on the type of operation you want to run (self service, in-bay automatic, express, flex serve). The startup prices for a majority of those can be around a million dollars or more. I would advise joining a group called TCW (TalkCarWash) on Facebook because you can get a lot of insight on what information/business tactics are used to run a successful wash from existing car wash owners, chemical suppliers, and service technicians. There’s also a market place version of the group which I think would benefit you as well.
