I've used the Station Auto Wash in Leesburg for my G35, FX and now E90 on the odd occasion. It's a multi-million dollar facility with an absolute wicked wash (yes, it does use brushes). They use pure (filtered?) water too!
You get the car hand dried, windows wiped, tires dressed up etc. They even do polishing, although it's just a wipe on and wipe off thing.
They made the whole place look like a "train station" hence the name. I've seen all kinds of high end cars there; MB, Lexus, Porsche, Caddy, Audi etc. Even saw a Maserati once.
It's the mother of all semi-automated car washes if you ask me.
