I've been going for the last 13 years. Most times it's a hoot with all your favourite motors knocking about. If you're on an official club patch your organiser will get tickets for some, not all, members. I don't do track in my show pony but plenty do. Other meetings generate numbers of the red mist brigade, which put your car at risk. Not so this meeting as the individual clubs steward their members accordingly.
It used to be the case that Combe gathered all the italian machinery together, without the 'them and us' segregation of Fezzers, Mazzers, Alfas and such, then everything else that seems the way at Brooklands etc.
The SFC used to have its varied collection of classics and modded motors occupying an adjacent spot to the X1/9 Owner's Club making for big numbers, but in recent years the italians have been spread all over the show.
If you're reading this and haven't been before, love all motors, not just italians, you'll be in 7th heaven mate.
