Yes, people love cars that look like big monochromatic plastic shells, nowadays. Just like taste in contemporary music.

I think the new cars are too bland. Need more chrome, and less plastic.

As far as the W126 looking dated. Depends on what year. If you have the post '85 models, they look very modern. If you have pre '85 models, they do look like classics.
