Pontiac was the only companion make to survive, and it almost went out in the 50s. Then came in Knudsen who turned it into a make with some dedication towards performance starting with the Bonneville. The Knudsen nose helped Pontiacs become recognizable until the end, and Pontiacs were probably some of the more easily recognizable cars from the 90s on. As fas as luxury options, after '73 just about anything had luxury options and Brougham. Had the Aztek not happened, and the GTO been closer to the 1999 concept, then Pontiac may still be around.
