Actually if you look at the maps that the Mercury News has posted, you'll clearly see that the car wash is among the properties they list as having been bought by the Google venture.The car wash at the corner of W. San Carlos & Bird is surrounded by a fence, along with the other adjacent properties.
As far as I remember, the car wash was never reported by the many Mercury News stories as being sold to Google.
I think Google is trying to keep more of these purchases under the radar & avoid the Mercury News' constant blabbing. I'm sure they're not happy with the publicizing of these inflated purchase prices. Makes their job harder.
I used to use that car wash once in a blue moon. Stopped after observed them washing manually with a big brush when they advertised as a "brushless car wash." Serves them right.
