The Telegraph are reporting of complaints from car buyers that they have been sold a car, which was owned by rental companies. So while it is technically a one owner car, it has had lots of drivers and potentially a rough life.
The full article can be found at the Telegraph website . We have had similar questions, which you can find elsewhere in our knowledgebase. Feel free to post more.
In the end, it shouldn't matter what the car has done before, provided it has been through a Used Approved preparation scheme and you are satisfied when driving it that it is what the dealer says.
Use the information in our Used Approved section to make sure that you have asked a dealer all about the preparation standards and warranty protection offered.
