meh.. i'm obviously going to have a slight bias... but i've also driven one for more than anyone here, as well as driven every engine/transmission combo. so while it might be biased, it's also based on actual first hand knowledge rather than someone else's formed opinions.
used, don't bother... as others have stated, the 2013 was a hodgepodge of confusion and mediocrity. too many of the options ended up getting cancelled, or later, included on other models... it will muddy the prices and make it very difficult to know exactly what you bought.
new, they are actually quite decent. best in class?... nope. but i'd say worth a look. the new 2.4L that is standard on all trim levels above the base or the aero version is not too bad at all. i found i could actually get real world mileage less in a new auto sxt than i got in my demo that was a standard transmission 1.4L model...
due to slower sales, most dealers have pretty competitive pricing on simple models. skip se models due to no ac and the 2.0L... GT and Limited are very nice, but too expensive and there are better things to buy at those prices... what to look at are sxt's with the lower level rallye edition... can be had for under 20k, have auto, air, 2.4L, power stuff, bluetooth, alloys, fancy track taillights, etc. and finance at low rates.
