That list of cars isn't the list of most popular millennial cars, it's the list of cars that no one except young people will buy. You're right, the GT-R, R32, WRX, IS-F, and Magnum aren't a "normal person cars", they're mostly cheap high performance cars. The other half of the list is cheap, ugly SUVs. That list is a list of unpopular cars that for various reasons sells slightly better to younger people.
