I have a 2013 as a company vehicle, I agree that it looks better than the 2014, but I'd be quick to live with the 2014 looks to get the ZF 8sp auto - the Daimler 5 spd in the 2013 is awful.
As for the rest of the ride, the ride, the features, the fit/finish are all really good.
I'll be up for a replacement in late 2014, I'll likely go with the Jeep again - hopefully the new look will grow on me by then.
