In my experience, they clean my car very well and leave it looking very shiny. Having said that, there are some issues that I have. Every time they bring the cars into the bay, I cringe so hard because they really should slow down when aligning the wheels onto the conveyor. Another thing that really annoys me is that they open the doors while your car is going through the wash bay and spray the inside of the door sills with water! I don't know who thought this is a good idea because obviously pressurized water gets everywhere. Is a damp towel not enough to wipe down the door sills? (No wonder people are complaining that there is a wet smell in my car!!!)
