This could be an interesting thread,as a competitor joining the historic racing scene in the early 80s it is quite different today.
The range of cars around then was quite wide ranging compared to today as we have gone down the path of one type classing ieFormula Junior/Formula Ford etc.
Lots of the older slower cars and specials seem to have gone or now in the vintage group.
We did have some weird and scary grid mixes in years gone by as a lot of meetings Historics were all lumped together and I can well remember racing the Buckler in the same race as a Formula 5000,you sure stay alert.
I have always liked speed groups as in this format you can have a mix of car types in the same race just keep saloons sports and single seaters separate.
