A private buyer bought the car over the telephone.
"At £19.6 million inclusive, it's a new world record by some distance.
"We had eight telephone bidders at the start of the bidding and we had three people in the audience, so we had more than 10 people who were prepared to spend. Of those 11 bidders, only five got the chance to bid.
"Our own personal record of £5 million was achieved last year for a Bentley. The price that we achieved today is over three times that, so it's extraordinary.
"We always knew that it was a very, very important car."
