The only legal way to move an un taxed/Mot/insured car is on a trailer.

Forget dollies,,, you fall foul of the unbraked trailer weight limit.
Forget Steerable "A" frames,,you fall foul of the unbraked trailer weight limit.
Forget a Rope or Bar, it needs to be taxed/insured/mot'd.

Watch out if you trailer it, you can easily fall foul of the Max permitted towing limit for the car/van and not haveing a licence allowing towing.
