I saw the car pictured above the other day, and those wings look a bit different to Cosworth ones to me, especially the fronts. Unless the Cosworth rally cars used slightly different wings?

Anyway, as far as I know...

You had the Grp. A cars which were standard bodied MK5b RS2000s, the F2 kit cat, which is like the one above with Cosworth style arches, and then the Maxi, which used the MK2 Escort inspired arches.

Suspension changed quite a lot between each car too, especially the rear end. Engine spec also got wilder as well.

Finding information seems pretty hard though, as there were so few of them.

Does anyone know if the white shell sold? I really wanted it, but I'm not rich enough
