Having attended the Formula Ford Festival at Brands Hatch a few times, I would love to have this car and other classic Formula Fords in the game. The closest I can get to that experience at the moment is to race the Red Bull Junior round Brands Indy on Comfort Softs - that combination laps close to real life Formula Ford times and feels good.
I would also like the Prototype front engined racing cars like Mallocks which were one of the mainstays of European and Nordic racing for a few decades.
