What are other nice sedans like the maserati quatroporte?

i want to get a luxury sedan what else should i look at?|||there's the king of all luxury cars: the Rolls Royce Phantom, but that'll run you about $400,000. I would probably say the Audi A8 is a luxury sedan. I really like the Jaguar XJ personally. I've also seen some very nice BMWs, and I don't know much about Cadillac, but apparently they make luxury cars
