Car wash / valet

[Gastons_Revenge]

I'm imminently moving into a property near Eastleigh soon which doesn't have an outdoor tap etc. for a pressure washer or hose, making car washing a bit of a faff. Anybody know of a decent self service car wash bay or inexpensive valet service locally? Preferably one step above the usual dodgy hand car wash guys who inevitably whack a gritty sponge on the paintwork.
