(UK) How many people have a project car?

If the car is in storage or a garage then I don't think you will need to insure it, if the car is not capable of being driven and is not near a public road I think they are going to have trouble trying to enforce this, I think the fact is people are filling in the SORN details and then driving cars about or are staging accidents with uninsured cars on purpose, insurance prices are getting stupid, mine has doubled in 3 years though I've not had a claim for over 30 years
