"Once a year my friends and I go to the bathhouse ..." (C) - Toyota Land Cruiser, 4.5 liter, 1996
It also happens - washing - after spring! (once a year)
Washings after rides are not taken into account, when the color is as close as possible to natural in a given period of the year and pieces of dirt falling off threaten serious damage to the “puzoters†riding behind on public roads.
