MEET the father-and-son car restorers who are turning rust to riches by buying, selling and fixing some of the world's rarest cars. Lance, 52, a former panel beater for Rolls-Royce, is now the go-to guy for bespoke classic car restoration - while Merlin, 20, specialises in sales and acquisition. Some of the rarest cars treated at their business in Brentford, west London, can be worth upwards of $19m. This week Merlin's classic car dealership Duke of London needs a permanent home, and Romance of Rust is running out of space and has a two-and-half-year waiting list for restorations.
