I don't know the exact cost, but if I had to take a guess, I'd say around 200,000 - 300,000 dollars. Depending on what additional onboard gantry features you decide to add to the main system.
@@momeater69 A Mark VII IBA would probably be better than this system. Especially their ChoiceWash XT because it combines both high pressure and friction elements which is what I believe most car washes should have these days in order to eliminate more dirt off a vehicle.
