I was going thru the UK ones and only seen one so far, but oh, so many cars in the driveway. Still looking for local ones, closest was 4 miles away. Part of me wants to find something local, drop a note thru their door.
Many have their location miscategorised though. I saw some with a town name on-screen which was different (but usually nearby) the city listed on the site.
They probably do an IP location lookup which tends to be pretty inaccurate.
