 I tend to drive decently roughly. I bought this car after minor body work had been done thanks to a tree collision (right, carfax?), and made off with it for $10,000 exactly with only 37,000 miles on the ODO. In my 10 months of ownership, there have been a couple warranty part replacements that Colonial Kia near Richmond VA handled with grace, but NO out-of-the-ordinary maintenance has been required. It’s one of the smoothest riding non-luxury sedans I’ve ever driven, but the suspension is taut enough to let you never forget there’s a road under you. The exterior paint seems pretty cheap, getting substantially beaten up on the front end by simple highway battery, but the Interior is too-notch. The leather-wrapped steering wheel feels fantastic, the controls are very intuitive on the steering wheel and on the dash, and the seats are almost obscenely comfortable, in my opinion (5’6 @ 145 lbs). Materials are the same in front and back, unlike in the Camry, and legroom is ENDLESS. Road noise is decently isolated. Wind noise can be burdensome at very quick highway speeds (like I said, I drive pretty roughly). The engine is quiet and strong, but the transmission kills the acceleration experience, hence the 4-Star review. There is a plateau between when the electric motor peters out and the Atkinson 4 cyl kick in that makes even RELATIVELY rapid acceleration very frustrating. The transmission shifts extremely slowly and smoothly, but at the appropriate times, especially out of ECO mode. I know some people struggle with fuel economy in their Optimas, but I’ve found nothing but truth in the EPA numbers, pulling down 36 mpg combined in the middle of winter in the mountains of New Jersey. 0-60 time is 7.8 seconds on my best runs (don’t ask me how I know this). Lastly, the car is just so damn stylish. Even 5 years after its release, it still looks pretty relevant, aside from that front lip spoiler. Final recap: its 6-speed transmission doesn’t make it feel as wonderful as it seemed during the test drive (especially when you first start up the car), but the electric torque does feel VERY good on slowish starts. The interior is vey high quality for the segment, although the trunk space leaves much to be desired, albeit the hybrid battery. The exterior is beautiful and seldom seen in the unique hybrid styling. It’s been incredibly reliable over the 30,000 Miles I’ve driven it, including a Canadian road trip and months and months of pizza delivery. Lastly, I find it supremely comfortable and relaxing to drive, as long as I’m not trying to burn rubber. In my hybrid. Because I’m THAT guy.
