Also on the subject of towing on an A frame apparently someone on this forum got done for no insurance for towing a car on one that wasn't insured however I have to admit that I was under the impression that once it was being fully controlled by the vehicle in front it became a trailer.
Nathan have you considered getting a lighter track car that you could tow yourself either on a dolly or a trailer. If it's light enough you don't need it braked you could build a trailer as a trailer is always the best option as then if the worst happens you can still tow it home even if it is a bit of a faf getting a 3 wheeled car onto a trailer. For under a grand and under 750kg you can get a dodgy 80s/90s kit car, a little kei car like a suzuki cappuccino or honda beat (very close to 750kg) or something very cool like a reliant kitten (RWD and easy to drop a bike engine in) or an old school mini just for a starters.
Reliant kitten (only just over 500kg standard), ripe for a bkie engine http://www.ebay.co.uk/itm/1977-Reliant-K...418bc5392f
