I enjoy washing my cars myself. These days in California to conserve water I use a cleaning spray and then a detail spray to wash my cars, I don't use water. Of course in my mild climate that is more feasible than where you live.
I have only used a car wash a handful of times in my entire life, and that was when I broke my leg 30 years ago and for a few months was unable to stand up long enough to hand wash my car.
