Yeah, the old S-klasse was gigantic. Much nicer than the new, smoother one. It's actually hard to tell the difference between the new S-klasse and the C-klasse. And THAT'S embarrassing.
I like the new BMW 7-series much better... although lots of people say it's ugly. I don't think so, it's one of the very few new cars that has some character.
If I had to buy a car for myself (with my own money) I'd probably buy the vintage and original Audi Quattro. You know... the model that Hannu Mikkola won the Rally WDC with (in the eighties). Kids probably wouldn't even recognize it these days, but I think that car had "cojones". The design is blocky and completely outdated, but it still kicks ass.
