1975 Ferrari 365 GT4 BB
- Colour
- Metallic blue ('Azzuro Metallizzato')

Chassis 18259 is a right-hand-drive Ferrari 365 GT4 BB, originally delivered to HR Owen in London in January 1975 finished in Azzurro Metallizzato over black Connolly leather, before almost immediately being shipped to Asia where it is believed to have belonged to Thai royalty. Returning to England in the mid-1980s, it passed through a small number of owners and accumulated remarkably few miles. Multiple engine restorations were carried out across its history, and by late 2015 the car had been returned to its original factory colour scheme. It retains its original engine and coachwork stampings, with an odometer reading under 4,300 miles.
