In with new, out with the old. That's what they say at least.
I don't know, I think I like W221 better than the W222. Granted, we still have yet to see official pictures but from the renderings, it just looks like a longer CLS. In fact, the front with the headlights are almost identical.
Going with that, I also think the R171 > R172.
I love Mercs, I truly do. What is happening though
They go from creating timeless designs (e.g. R171 and W221) to big nosed-flat faces. They're trying to make their cars more aggressive, but it's just not working. Stick with the classy looks MB, we dig it. If we wanted performance and aggressiveness, we'd go to BMW. Despite being an MB forum, I think many will agree with that as well.
I will say that I think the new Cs and Es were done well. They previous models didn't age well. The W212 has been especially controversial, but definitely an necessary update from the W211 IMHO.
Do we know if the new S is going to be a 2013 model or released in 2013 as a 2014 model yet?
