Well, I'd say the Lincoln MKZ is a good looking concept...
2012 Lincoln MKZ Concept
They made it distinctive from the Mondeo, and that is a step in the right direction. Lincoln wants to make themselves a different kind of luxury option from BMW and Mercedes, which means they no-longer want to beat around the bush with Cadillac either. Not a problem, they will fill a niche, but when it's already occupied by Buick and Lexus (well, if Lexus decides to stay)... I'm not sure what they're doing.
2012 Acura ILX Concept
Well, this is the first-time we've had an entry-level Acura sedan, as a compact, since the Integra. Not a bad thing. The Canadians have their one. This one seems to be alright. I'm interested to see how they make it distinctive enough from the Civic, but a K24 can't be the only way of doing it.
2013 Buick Encore
This one was ignored a bit more than it should be, I think. Yes, its a crossover and a lot of people don't like them, but... Its the first one to be based on the Gamma II structure beneath the Chevrolet Sonic. They did not say if it was to be offered with some kind of 4WD/AWD system, but I imagine that it would. Matched to the 140 BHP turbo from the Sonic/Cruze, fuel economy should be friendly for those looking to get a high-riding hatch.
Chances seem high that we'll get a Chevrolet version of this. I still firmly believe that this is an untapped market here in the US, as I'm always quite jealous of what they offer in Europe. An affordable, fuel-friendly, 4WD hatchback is perfect for urban/suburban folks in the snowbelt.
