Kia Motors UK already has the longest warranty on the market - seven years for European-built Ceed - and now plans to backdate it as part of its new approved used car scheme.

All used cars under 18 months old, or with less than 15,000 miles recorded, will have their warranty 're-wound' to what it was when new - three, five or seven years.

It's an interesting move from a group becoming known for marketing innovations. Parent Hyundai Motor recently launched a finance package in the US that allows penalty-free return of a car if the buyer loses his or her job, subject to some conditions, as you'd expect.

Kia UK's fleet and remarketing chief Andrew Sellers, said: "This is a statement from the company that we are confident in the reliability of our products and our warranties. We are also offering a class-leading 60-day exchange plan which no one has offered before. Along with multi point check and seven-day drive away insurance.

"Most companies offer between 14 and 30 day exchange plans, but we are saying that if there is any fault we cannot rectify in 60 days, we'll change the car."

Kia's new 'approved used car programme' is now called just that in place of a previous scheme called Kudos.

Sellers said: "With Kudos people did not really know what it meant. The new programme does exactly what it says on the tin. People understand what it is. It is not a new brand."
