The LS has some S-class lines but the GS doesn't resemble any Mercedes. Japanese automakers are famous for copying a product and making it better than the original. I've driven plenty of Mercedes vehicles. I agree they are nice but prefer the reliability of a Lexus/Toyota. If you want to see a real copycat, take a look at the new Hyundai sedan. Wait until you see it from a distance in low light. You'll be thinking Lexus/Mercedes/????
