In reply to Removed User: The first one was filmed all around where I live. If you know the film well you'd recognise a lot of the roads and views around here (although some have changed quite a lot since the 1970s.
I went out to Silverton (?? I think it was) once, and had a look around, there's a little pub where everyone used to hang out during the filming, that have a replica of the interceptor... got a ride in it !
