I'm a big fan of Goodwood Circuit and the vintage racing held there, not so much the Festival of Speed (though I quite like the name). Anyway, here's a series of Can-Am cars of varying vintage running both the circuit and hill climb. Of particular note would be the fourth car in the video, the McLaren M20, not so much for the car but the driver. "R. Attwood" is none other than Dickie Attwood and he was probably 78-80 years old for this run...and he still makes appearances in historic racing events to this day.
Gotta love those Lola T70 spyders (though I was actually a big Chapparal/Jim Hall fan). USRRC and early Can-Am was just a sweet spot in motorsport history.
Those Lola cars are beautiful things. Haven't even thought about those in decades...
