Bentley Corniche Convertible Hire

[andyps]

Does anyone know if it is possible to hire a Bentley Corniche convertible, preferably in the North West of England? It is my Dad's 80th birthday in September and when we were at Le Mans for the classic last year he saw one and said that is what he would like for his 80th. Unfortunately I can't afford to buy him one, but if I could get one to chauffeur him around for the day that would be great so any ideas gratefully received!
