The offer follows a successful trial that launched at the start of the year with the Terios mini-SUV and Sirion five-door supermini.

Now, both the Copen sportscar and Materia mini-MPV will also come with five years' unlimited mileage warranty plus five years' UK roadside recovery.

The extended warranty package relates to retail sales, and will run to the end of 2008, at which point it will be reviewed.
