I use automated car washes, brushless or brushed it really doesn’t matter. At the end of 2-5 years of ownership I doubt the value of the car is going to be significantly different between my car and one that was pampered by hand.
It's not about the value at the end of ownership. It is about how amazing your car looks during ownership!
I personally like to wash my car by hand, it is therapeutic for me. A nice wax goes a long way to keeping the car clean as less can stick to the car. I use mostly Meguiar products also.
