The Viper owner's manual recommend against bringing the Viper to commercial car wash. Does it really matter? Do we all wash our Vipers ourselves? How often do you wash your Viper?
Sort of an odd question since those of us who don't or can't "wrench" our cars ourselves, find it rewarding to at least do the weekly wash and wax. As other's have mentioned, the major problem with automated car wash systems is their "propulsion system". Most move the cars via the wheels and our Viper wheels are generally too wide to fit in the typical car wash tire "lanes". Also the height of the cars can be problematic.
But my memory of automated cars wash systems is rather old since I haven't been to one in quite some time. I know most are now "brushless" which is much better as the brush sytems actually scratched the clearcoat. But, the brushless systems are pretty much cleaning your car via massive leaf blowers, which is ridiculously ineffective.
If you can't wash and wax yourself, have someone professional and responsible do it for you ... by hand.
How often you wash depends on how often you use your car, in what conditions you use it and how clean you want to keep your car. Simple.
