ROFLMFAO - I suppose this is the equivalent of the early days of mobile phones when they had dummy phones for sale for sad t**ts to pose and talk to themselves.sym said:.......obviously because they look cool ! Can be stuck on, and don't require a hole in the roof (But only if painted body colour , and not forgetting that it serves no useful purpose at all !!)
I prefer not to advertise the fact that I have GPS, so my aerial is nicely concealed under the dash. Didn't fancy drilling a hole in my roof either . . but hey, whatever you like !
