It's all about having the ability to travel through time & space. I was granted this gift back in the late eighties when I provided a jump start from my A60's battery for an alien chap who had put his space ship down in the car park at well-known Southern classic vehicle show "Auto Sunday" which was happening by Bracknell, Berkshire. The friendly alien had come from a far distant galaxy as he'd heard that one of the autojumble stallholders was stocking new/old stock dilithium crystals that were compatible with the space ship. Sadly, the lengthy storage had meant that these crystals lacked the ability to start the ship's warp engines and as the A60 had such a whopping great massive battery on it, I figured that a jump start might just get the alien's vessel running which, fortunately, it did. Once he reached space, he was able to travel downhill for long enough to use regenerative braking to get the crystals working properly. We still exchange Christmas cards and I have an open invite to stay on his home world any time I'm free for a while.
You should see the place, they have a very active multi-make car club there and the beer is only 3p per pint.

I found the Mazda's details by pure fluke, based on the premise that somewhere, there would be a link back to the source of the original image of the car and that this image would show the registration plate as it was before Mr P. Aranoid made his crude attempt to disguise [the plate].
I also found an image of the Mazda's owner posing naked with a pair of Rottweilers. Honestly, some people!
By the way, I had written the above
before I clicked on the link to the Cortina-based camping device. Honestly, I had, but that does look a lot like the friendly alien's daily runabout.
The Crayford Cortina looks good, IMHO, what a shame the folk who did the Mumford Marina

hadn't been blessed with the same level of skill as the designer of that!
