...but there is no pleasure in answering only the ones we already know.
I find interesting also look for new cars and obscure ones. If I just have to solve the (for me) easy ones, probably I will show the world how many cars I know, but wouldn't that be more boring?
I thing you have an higher knowledge about british pre-war cars than anyone, but why don't you try to solve the british pre-war cars in the upper sections? No doubt you know the Alvis and the AC...but wouldn't be more challenging for you cars like Arbee, Gilburt, Orpington, etc?
