I suppose I'll be the guy that makes the others cringe about how I wash my car.
Here in the Chicago area, I have a $15 unlimited monthly membership at the local Jet Brite conveyor tunnel wash (10 locations near me) which uses soft closed cell-foam brushes. These are far less abrasive than the nylon bristles that used to be in auto-washes. It also includes underbody blast and power washing the wheels. It probably helps that I have a pearl white car, but I can't see any swirls on the paint since I bought the car in August. I've only applied NuFinish once right after I bought it, and didn't do any expensive ceramic coating. Perhaps there are micro swirls or fine lines that would be more evident on a darker color car, but mine passes the
"looks great from 2 feet away" test for me.
The downsides to touchless systems to me is that they rely on harsher chemicals to clean the car. That can take its toll on your plastics, trim pieces, and paint coatings as well. Of course, there isn't anything physically touching your car, so one would avoid any possibility of fine micro scratches or swirls. But too often, touchless still leaves some grime behind, which leaves one with the need to wipe down or hand-wash it later which could also introduce swirls and scratches if not done carefully.
Those that have the time and agreeable weather to perform the foam and 2 bucket hand wash in their driveway on a regular basis will certainly have a better "show car quality" finish, but I don't have the time, desire, or need for that with my Stinger as a daily driver that I'll trade in after 2 or 3 years.
There are certainly pros and cons to the different ways to wash you car. An owner just has to decide what's most important to them. For me, it's a durable coating (pick your favorite polish/wax/ceramic) and the convenience and low cost of running it through an auto-wash. For others that have more time and concern for the finish of their vehicle, I can certainly understand why they do it their own way.
