I would never bring the NSX there. The only reason I even take my AMG through this car wash (since it is not a hand wash) is that I need to take clients around and sometimes I have no choice. I doubt they have ever even seen an NSX that is why I was surprised to see the posters everywhere.
Not to mention the possibility of a yellow, orange and blue 02+ going to a car wash together... umm, come to think of it, will this joint get sued by Honda by stealing their Brochure picture for advertising??
