I can't recall whether I got it on here or not but there was a magazine advert in the late 80's/early 90's that featured a police box on car wheels (possibly the 30 years in the Tardis police box without white windows). I used to have a copy of the picture but can't find it.
Does anyone have a copy of this picture that they could post?
I know exactly which one you are talking about. Unfortunately, the only place I remember it was at was the old Police Box History site prior to Glenn taking it over. You can try images.google.com and do a search fo TARDIS and see if it comes up. Bill Rudloff
