Joondalup/Edgewater should be high enough but they don't like dirty cars..........
Why are you a car wash and don't like dirty cars?
There seems to be a car wash with a ramp around Armadale.
The guy who owned/managed it is in jail from what I heard (I'm not going to go into what for because its hearsay.. but what I heard was not nice)
He was the instigator of the 'dont bring dirty cars here' policy and would stand out the front and watch cars come in, he had NO problems telling you to leave if you had mud on your car, He told me it was a City of Joondalup rule (bollocks)
He also told me I could not vacuum the back of my Navara (which had a draw system/carpet in it) because it was a "commercial vehicle"
I stopped going there for a while, but now he is gone there is a different guy running it who doesn't seem too bothered by much at all. I still tend to go out of hours, but that's because its quiet.
Having said all of that, I have never used the auto wash, I generally use the bays and less and less now because I usually need to clean the camper too and its easier to use the pressure cleaner at home!
