I once had a ride in one (although it could have been an M1B) up the hill at Goodwood. It was on the press day (to which I'd snuck in!), which they stopped doing at the house only a couple of years ago. By that point there were 150 or so cars there and it was a bigger event than the first couple of FOSs, with considerably fewer people. I'd walked down the line of cars ready to go up the hill (they always took journalists for a ride, if they could fit in) and asked Dickie Attwood if I could go in the 917 (no room) and Justin Law in a XJR-9 (no room) before getting to the McLaren and being told I could have a lift if I could fit in and the driver could still move his elbows. The engine noise was deafening but the acceleration away from the line was unbelievable. I filmed it and you can see the start, then tree tops, then a corner, then the sky and so on it was so brutal. Afterwards the driver apologised for being so cautious and slow due to the tyres not being warm enough...
