So why should you care about historic racing? Not everyone does, so why does Autosport give the Goodwood Revival, in particular, so much coverage?
For a start, older machines give many motorsport fans what they say they want. Barely a week goes by without Autosport receiving correspondence lamenting hybrids, the move towards electric racing, or the scourge of downforce, and many aren't happy with the proliferation of single-make categories.
But all these things - particularly the alternative-powerplant technologies - are here to stay. That's where the world is going, where the manufacturers are going, and, ultimately, where the sport has to go if it is to survive in the longer term.
