I did the same. Thought of names and tried to insert them. Why not accept "Rolls Royce" or "Vauxhall" there isn't any "motors" tagged onto the car brand, it's the company names. And isn't it "Morris Mini"? The selection of cars seems somewhat random. Oh and why is there one times England and the rest United Kingdom?
Surprised Lincoln and Mercury were not on the list.
Tough quiz, at least the way I took it, thinking of names then trying to plug them in to the correct slot.
