There is both a 2006 and 2006.5 model this year. The early Optima LX features a 2.4-liter, 138-hp DOHC I4 engine, while the 2006.5 ups the horsepower to 161. The old 4-speed manumatic is replaced with a 5-speed manumatic, while the 5-speed manual carries over. Both models of the Optima LX come with full power features, cruise control, split-folding rear seats, a CD player, tachometer, and dual front-side airbags. The 2006.5 Optima LX upgrades to larger 16-inch wheels, a security system, adds front and rear head airbags, puts audio controls on the steering wheel, and adds a tire monitor and heated mirrors. The front-wheel drive Optima LX is equipped with an independent suspension and front and rear disc brakes. While a rear spoiler is the only option on the 2006 Optima LX, the 2006.5 offers 17-inch wheels, leather trim, automatic headlights, foglights, and a trip computer. Owners feel both the 2006 and 2006.5 Optima LX is a good value for the money, considering the long list of features. They do wish ABS was at least an option, and there are some complaints about an uncomfortable steering wheel.
