I have no problem with taking the family car through the tunnel washbut when it comes to my personal hobby-toy I won't let anyone else touch it. How about you?
I normally put mine through the local car wash. Saves a lot of time and effort. I've always hated hand cleaning cars. Because I hardly do any mileage, works out cheaply.
I always wash my own car. It's been through a car wash once in its life with me...I don't trust those things around my pretty painted car. Sometimes I do use the self-service ones though. I like to wash my car in the sun when it's hot out...makes for some fun times as well!
My Oldsmobile has too many things on the outside missing, so a tunnel wash wouldn't take me even if I wanted to! LOL We hand wash our vehicles ourselves.
