What New keeper slip (V5C/2) means for you
Check the logbook before you fill it in. The name and address should match the seller's ID, and the VIN should match the car's windscreen, door pillar and logbook. If the car was bought on finance, the finance company may still own it until the last payment, so run a finance check first.
Once the sale is done, the new keeper details go to the DVLA. Make sure the car is taxed before you drive it, because car tax doesn't transfer to a new keeper. Keep the car insured and ask for its MOT history.
