I don't get it - would you would think you can hose out a consumer car like this, with the fabric seats and all that plastic trim? I've hosed out Land Rovers, but they're clearly an off-road vehicle designed for wading.
I was looking at one of these at the dealership in the early 2000's and the sales guy told me I could just hose it out after a day at the beach. It seemed plausible considering there was no carpeting and the seats could be folded up.
My buddy bought one and he would hose his out all the time.
