Total rip off - go here if you love being taken advantage of. I have a corvette, and they claimed that their new policy is that because it rides so low, it has to go through a 'special' process that costs almost double the price of the basic wash. Bullshit. I've been there multiple times and it went through the machine just fine. This is just the new management's way of trying to make more money off of people they assume can afford it. Nice expensive car? Let's charge them double for the same service!
Don't worry guys, there are plenty of honest car washes out there who do a better job than you do. And I passed this information on to the corvette club I belong to also.
