Once you have the paint polished to the degree that makes you happy, and I'm pretty happy with the paint on my truck, then it's real easy to quickly wipe it down.
Of course, not having any plastic, vinyl or rubber trim to spend time avoiding, just pure paint, chrome and glass, plus, not having to bend over, makes it very easy and fast to wipe her down. If it were more complicated, I'd probably slack off a lot more and just wash it every other week or so...
Serioiusly... it's pretty hard to find anything easier to wipe quicly...
Even the wheels are easy and fast to wipe clean or wax with a spray-on wax plus my fingers fit into the slots between the spokes.
