All,
I have spent some time looking deeper into the differences between the older Alfa, the newer Alfa and the Opel and Mercedes. I have a list of the cars, along with all the information about them. Please use this information when selecting a car to run in the series.
I am still not opposed to having all A group racers run the Alfa and the B group racers the Opel. We will have to see how they compare before we make a final decision.
