what is luxury car of toyota
They are luxury arms of mainstream brands. Lexus is the luxury arm of Toyota; Infiniti is the luxury arm of Nissan; Acura is the luxury arm of Honda. I would not say that Maybach is the luxury arm of Mercedes-Benz, since MB makes luxury cars that compete with Lexus and Infiniti. Brands like Toyota, Nissan, Honda, Volkswagen, Fiat make mainstream cars.
