Extending Warranty on Bentley Continental Supersports?

[Zanderman]

Hi All,

Does anyone know if it is possible and if so the cost of extending a Bentley Continental Supersports warranty? The car I am looking at if from a non Bentley dealer and is under Bentley warranty until early next year. The car is approx 5 years old. Also can you just extend it or do you need to get it checked over first?

Thanks!
