Damn! you hate Mazda with passion, don't you?
Anyways, what I talked about recent Chrylser concepts I was thinking of the Nassau in particluar. Honestly I don't see anything interesting in that concept.

As for the Arrow design, I don't if you mean what I'm thinking of, but Mercedes has been having pointy fronts for ages. They left this direction for a few years in the 90's but now they're back to it.

The PT-Cruiser hasn't been inluental IMO. I'd like to use the term "Reminding". For me influental design is original. fresh design. But when you reinterpret something that's been there for ages, you "remind" people that these things once existed. I'm in need for word now. Not sure whether you get what I mean.
