We've been on a monorail train, ridden an open top omnibus, seen 4 land speed record breaking cars. Hung with cars from the dawn of F1, admired many classics (some stunning Rollers).
Famous cars have also turned up including Ari Vatanens Escort RS1800 WRC winning car (1980), some motorbikes that caused me to experience a major trouser tent, the Ford Anglia that flies from the Weasley household (muggles beware), Del Boys Trotters Independent Traders Reliant van and Marty McFly's time traveling de Lorean.
If you've never been GO! If you love cars and bikes GO! If you've got no life GO!!! It rocks, it is the first time I've been there in quarter of a century and it has only got better

Even the Victorian gardens are drop dead gorgeous.
