You know Sam, normally I'd run far, far away from anyone but me washing my car. But, considering my car is 3 years old, it has very few swirl marks and I don't think there's any discernible difference in the paint since the dealer has washed it a few times compared to before. Heck, my car's CPO so it probably visited the car wash many times prior to me taking ownership. Also, it's white so swirl marks aren't really evident anyway when they do appear. I gave the car a nice bath, clay bar, and wax before the foul weather set in and I'll do the same once the weather finally breaks. The wheels are atrocious, however
