He was an OK club racer but only really shone at Brands Hatch, in fact he was sponsored by the circuit at one time and that's how I think he got his start in cars, being Graham Hill's son helped too. To be fair to him when he was driving in Formula One he often said in interviews in the UK that bikes were really his first love and his wife always maintained she preferred being around motorcycle club racing than big time car racing. I'm a little biased though because we grew up a few miles from each other and he was quite popular in the area.
