I now have to drive year round after getting my number one car.. i don't drive it but 400 miles or less within 2 weeks or a week and a half.. so that is good for mileage.. but.. yeah.. since the snow is out and everything.. i intend to wash it on wendsday.. it looks kinda beat right now.. which for me is alright.. b/c it makes me worry a little less when i have to park it somewhere.. but yeah.. when the snow is gone and salt and grime is off the road.. i will wash it about once a week and clean daily about twice a week.. it's kinda pointless to do it that way if there is all that stuff on the road now.(wish i could wash it more.. but i don't have the time for my z3.... )
