This car is amazing, after dismal repairs on my 2009 Honda Accord EX-L, I gave in on my frustrations and traded in the car for a brand new 2012 Kia Optima EX with Tech and Prem packages. The car is so much nicer than the Accord and a pleasure to drive. I have already put 3k miles on the car in one month because it is so addicting to drive and it turns heads wherever I go and people always ask "That's a KIA?" I highly recommend it and don't pass it by because it is a KIA, the brand has made drastic changes and it definitely shows. My Honda Accord was my third and last Honda and I will not be going back.
Power folding mirrors, navigation system, ventilated seats, iPhone/mobile phone media integration for streaming music
The only improvement I can think of are:
LED headlamps (daytime running lights)
Add daytime running lights, the Sonata has them and I don't understand why the Optima does not.
