Sir Elton's Bentley is finished in Onyx Black, with 21” Speed alloys which have recently been refurbished. The options on the car are plentiful. There's four full A4 pages of options on the car, including an interior finished in Beluga leather with contrasting Hotspur Red stitching, and a number of carbon fibre fascia panels.

The car is powered by a 6.0-litre W12 engine which is good for 626 bhp. It has a comprehensive service record, complete with the owner’s file with the service booklets, which show various stamps from Bentley Berkshire and H.A. Fox in Guildford.
