Don't worry about locking it - I have nothing to add.
Cegga stands for "Claude et George Gachang, Aigle" so a Cegga and a Gachang are effectively the same make. I was really saying that this car cannot be Maserati-based as I can't think of a Maserati model that they could base it on. Hence this would be their own chassis with a Maserati engine, ie a Maserati-engined car but not a Maserati-based one. (The reference to Porsche is simply because Porsche did produce cars that someone could modify so you could have a Porsche-based car - nothing more)
