This is not a list of those that have entered, rather one that shows who have had an auto entry and if they have taken it up.
In addition to those listed, we could add the 2 Audi R10s for Muckle, 2 P1 Astons for Prodrive, the Goh P2 Porsches plus the usual odds and sods from Courage, Pesca , Lola and Zytec into both P1 and P2.
I very much doubt we will see a grid as empty as we did in the early 90's in fact think it will be the usual 50+. I wont comment on the quality.
