What SORN means for you
A SORN is kept off public roads: once notified, the car must stay off them. The keeper then needs no tax or insurance. A buyer should know a car can't go back on the road until it's taxed, because tax doesn't transfer to a new keeper.
Before you buy, check the car's tax status and MOT history on a free check. Gaps in MOT history can show a car has been off the road. It also needs a valid MOT and insurance before it's driven again.
