Interesting topic. I'm surprised no-one has mentioned Mansell's win at Silverstone in 1987, where he had a puncture, pitted, came out 28s behind Nelson Piquet, in the sister Williams, with 29 laps remaining and passed him on the final lap. I believe this was Murray Walker's favourite F1 race. Another one I particularly liked was Mika Hakkinen's win at Indianapolis in 2001. Not a great season for the Finn, but this race was one of his best performances. After qualifying, he was demoted a few places on the grid for some infringement which he regarded as unfair, and no-one was giving him much of a chance. Mika approached the race in a state of controlled rage. During the first stint he ran quietly fourth, stayed out for longer than most, then unleashed a series of brilliant fastest laps which allowed him to take the win. Nice work - what a champion!
I was there for that one, great race
