In July I bought a 2014 Boxster in great condition. The manual says not to take it to a car wash. I have heard stories of car washes penetrating the top and getting water inside so I assume that was the reason not to take it to the car wash. I have washed it by hand a few times, but now that it will be getting cooler soon I may not want to do that. I recently met someone who has the same car and he told me that he takes his to a "touchless" car wash at a local gas station without any problem, and that the reason that Porsche says not to take it to a car wash has nothing to do with the top, but because the clearance is too low for the tracks that move the car through the wash. So what is it? Will a car wash that uses pressurized water penetrate or damage the top, or should that be OK? I don't mind washing it in my driveway myself on a nice day, but I will be driving it a bit in the fall before I put it into winter storage and I don't want to put it away unless it is clean.
