Tom Wheatcroft had an exact working replica of a 1903 ??? Bugatti Royale built to go on show at the Donington Park Motor Museum, it is stunning.
If you don't agree with replicas he also has an unrivalled collection of hundreds of the most important racing cars from over the last 100 years. I would guess that the has the best collection of Grand Prix cars anywhere in the world, the range goes from 1900's all the way up to the 2000's and has cars from every manufacturer who ever made a racing car - Alfa, Maserati, Ferrari, Auto Union, Ford, Lola, Lotus, BRM, Brabham, Tyrell, Renault, Mclaren, Williams .................etc, etc. It doesn't just include GP/F1 cars, there are other world series cars including LeMans, and Mille Miglia and Targa Florio cars. He has too many cars to mention including numerous championship winning F1 cars. He has a hall packed full of approx 50 McLarens and Williams'. if anyone is ever in the East Midlands, a visit is highly recommended. My son and I normally go a couple of times a year and it's a great way to spend a couple of hours.
