Buyers seeking a full feature load will want to consider the 2006.5 Kia Optima EX at $19,995, including an automatic transmission. The EX models have alloy wheels, fog lights, solar glass, chrome door handles, metal door scuff plates, a trip computer, foot well lights, door courtesy lights, and a leather-wrapped steering wheel. But the main reasons to choose the EX over the LX are for its eight-way power adjustable driver’s seat, automatic climate control, auto-dimming rearview mirror with Homelink transmitter, and 360-watt Infinity audio with six-disc CD changer and cassette player. If you want a bigger and hungrier engine, the EX V6 adds horsepower, torque and dual exhaust outlets for $21,000.
