Yep...the VSCC is the Vintage Sports Car Club as Joe Rides posted.
If you like pre-war cars, the smell of hot oil, noise and man-in-a-shed engineering then go to a VSCC race day, or hillclimb, and have a look around the paddock.
You will see some fantastic parts(lots of brass bits) and an eclectic mix of cars, with lots of history, driven with great gusto. Aero enginned cars, Morgan 3 wheelers, chain driven cars and Austin 7 single seaters with superchargers are the norm. The Austin 7 engines are bonkers now and anyone who knows of them might be amazed to hear them at full chat and to know the normally aspirated race engines are now around 60bhp, rev to 5 figures and cost about £12k. Probably more now as that price is a few years old from back when I was involved.
Head to Goodwood for the VSCC sprint which kicks the year off, or the VSCC hillclimb at Shelsley Walsh, or the VSCC race day at Silverstone. They are a very much out of place at Silverstone though they do get to stretch their legs and attracts the big aero engined cars, but the hillclimb venue or Goodwood feels and looks right. The Goodwood sprint was free to spectate at but maybe you have to pay now but at least you don't have to dress up like Marilyn Monroe or Churchill!
For slightly newer cars a really good meeting to go to is the traditional end of season HSCC(historic sports car club) day, at Silverstone. They normally have open-wheeled and closed-wheeled 'allcomers' races where you might see an old F3 against F5000 and Minis against Lola T70's. Other races will be the normal HSCC fare of period saloons, sports, GT, single seater etc.
