Car Wash for Mini SE

I wash the car myself. The main reason for a car wash is I really can't do much about an underbody wash, which is a good thing to do occasionally , especially living near salt water. But for what it's worth, when I wash the car, it includes fully drying, doing the wheels, and even the tires. So it's a lot more like a half hour than 10 minutes. And that doesn't include fully vacuuming the seats and the carpet, polishing the dash and controls, and taking out the mats and cleaning them. I guess we have different opinions about what a "clean car" is.
