As the full-size sedan segment continues to shrink, Kia takes a big risk with an early redesign for the Cadenza sedan. Slightly bigger than the best-selling Optima, this second generation features standard V6 power, a swanky interior, and premium looks to match. Those of you who won't be caught dead in an crossover but don't want to spend twice the price on a luxury badge should put one high on your list.
