My wife's new car is a Satin Metal SX w/tour and tech pkgs. and trimmings.
She drove both the 2.4 EX and the 2.0T SX and preferred the latter hands down driving the same exact test route and road irregularities. She didn't feel the need to drive the EX w/Turbo after that. For some reason the SX with the Sport tuned suspension actually feels more refined. The car is very new so no long term data from me as of yet but I cannot imagine getting more for your money than what KIA is now offering with the Optima. The overall level of refinement more than makes up for the few hard plastic bits found in parts of the interior. The 2.0T has amazing torque from 1250rpm with no lag. Yikes!
Avg. 28 mpg.
Engine, 6 speed auto, Nav and Infinity Audio system, 3 series style driver tilted console, comfortable seats (at least in the '12),
very precise handling for a mid size sedan, gas mileage, 2 position memory seating, heated and cooled front seats, heated rear seats, Smart Key technology and the dual sun/moon roof.
Better Voice recognition for the Bluetooth Phone connection in the NAV system. Shouldn't have to edit your internal phone listings in order to get better functionality from the NAV electronics. Needs work. Touch screen still great though.
