Found a donor - how to get it home?

[DStanley1809]

I need to get my new donor car to my house from 15 miles away. I've been trying to find out the legality of towing it with either a rope or a bar (I have either readily available) but it seems to be a bit of a grey area with regards to tax, MOT and insurance.

Some information says the car will considered a trailer if towed behind a car so won't need it's own tax etc but other information says to have any wheels on the road it will need it's own. This would mean I need a trailer.

Does anybody have a definitive answer on this subject?

Thanks in advance,

David
