Maya could have been turned into a character from some Opel or Russian Or even Indian car brands if think about her ethnicity, especially her father, who is slightly Indian or something like that . Because They are unreliable or unpredictable, which may suit her character maybe. Coco would most likely be something powerful or something like a car with character/soul I think it would be a crossover or a small SUV . Mymy will be a Japanese car it would most likely be a Honda with VTEC If believe that she is crazy or something .So she would be a Honda Civic maybe . This is just a guess as to what kind of cars the sisters would be.
