What Registered keeper means for you
The registered keeper is the person named on a car's V5C logbook as currently responsible for it. This can differ from the legal owner, most often on hire purchase or PCP, where the finance company owns the car until the final payment.
When buying, check the name and address on the V5C match the seller's ID, and that the VIN matches the car's windscreen or door pillar. If the seller isn't the named keeper or details don't match, ask why before going further.
