How much would a completly restored 1966 English Rolls Royce sell for?

Considering that a 1969 Mercedes-Benz 300SEL with the 6.9 DOHC aluminum V8 goes for $300K+, I would think that a Rolls, properly restored would go for at least twice that.|||how many miles does this car have is it running well any damage u can always try the Kelly blue book on yahoo autos
