The discounted price on some of the brand new UK registered cars that are supplied by us has been achieved by being originally "Fleet Registered". In some circumstances this means that the V5 (known as the "registration document" or "logbook") will show you recorded as the second keeper.In these circumstances we will retain the V5 for a period between 2 to 6 months from the original registration date (depending on the manufacturer/supplier). The V5 will then be forwarded on to you directly from the DVLA once the relevant period has elapsed.
