I've noticed I've been washing mine about 2 - 3 times a week.. //content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif
i do it when ever i can or when it gets too dirty. also when i want to look fly. washing my car takes me well over 6hrs of detailing so i don't have the energy to be washing it every week like i used to when i initially bought my car.
I rarely wash my truck. I can see all the scrapes and nicks in the paint when its clean, lol. So she normally stays pretty dirty. That and its pretty well a work truck so how "clean" it looks isn't a big concern.
If I had a nice vehicle I'd wash it on a weekly basis but I've never really owned a "nice" car so its hard to say.
but virginia has crazy weather so sometimes its once every few weeks //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
on top of GA having a water shortage, i park in a construction site everyday and it's a lost cause to try and keep either the inside or outside of my truck clean nowadays...
