I need to run mine through the car wash before it is closed and the wait time becomes 5 months. It's a tricky balance, last year I missed the timing of the car wash, but with the temperatures dropping, I already had to tug my door open once. Oh well at least it did get at least one wash just before tire change over time, and I may get lucky and fit another one in.
They never close here, although I'm sure they don't get a lot of business after it gets real frosty.
Except maybe the first decent day after snow melts when everyone is trying to get the road salt back off. :)
