The UK-based motorsports and engineering firm specializes in delivering the ultimate track machine by acquiring authentic F1 cars, restoring them, and selling them to passionate racing enthusiasts. The company surfaced a few years ago but has now produced a documentary detailing everything that goes into one of its cars. TDF says it hand-selects the cars and conducts thorough inspections, verifying their authenticity and race history before acquiring them. With years of experience running historic F1 cars for private owners, TDF has redesigned many of the fragile components and intricate operating systems typical of F1 cars, making them more durable and reducing the need for frequent servicing or trackside assistance. TDF’s F1 cars are available in the U.S. through O’Gara Motorsport, which also provides driver training and hosts track events, typically held at The Thermal Club near Palm Springs, California.
