In my class we were discussing the correct order of adjectives in a sentence. As the placement should be according to 1. opinion, 2. dimension, 3. age, 4. shape, etc., we were somewhat confused when it came to a sentence I bought a beautiful expensive fast American car. We agreed that expensive should be an opinion. But what about fast - is it a dimension or an opinion? What should be the correct order of the adjectives here?
I bought a car
I bought an American car
I bought a fast American car
I bought an expensive fast American car
I bought a beautiful and expensive fast American car.
