And the buying public began rejecting it in a big way starting in the late 80s, after which GM started trying to make them look more distinct from each other and mostly failing. This was the rule of thumb from that late 80s - early 90s era (and yes, this is an oversimplification): Chevy = base car Pontiac = Chevy with vinyl siding glued to the side and orange lighting Buick = Chevy with more options standard aimed at older people and the hood opens backwards Olds = Chevy with a different mousefur interior than the Buick, also aimed at older people Caddy = Chevy in a party dress with more gadgets. With the exception of the Caddy, they barely even bothered making them look different from each other. And lest we forget... Saturn = We tried to clone the 1985 Corolla, left out the long term quality, then we stuck swoopy bodywork on it and shipped it in 1990 when there were far better cars available.
