IIRC, the Jetta is made in Mexico and it doesn't have a very good reputation regarding its reliability. I haven't looked at it much though.
The one I'm looking for right now, based on my researchs on safercar.gov, the IIHS web site, manufacturers' specifications and various reviews is the Chevy Malibu 2014. It test very well on impact tests and the 4-cylinder engine doesn't need a lot of fuel (8.0L/100Km in city, 5.3L/100Km on the highway). It comes with subpar tires, but that's history after a few thousand miles when you replace them. The Malibu depreciates quickly though. Last year's barely used cars dropped more than 6000$, quite a lot more than something like an Honda Accord. So I might wait until next year, hoping my car last until then (it's more than 10 years old now and I drove approximately 265,000Km with it - it's totally trashed) and buy one second-hand.
