Kia dealers started receiving shipments of the 2006 Rio and Rio5 in September. Company executives expect 75 percent of buyers will opt for the LX sedan, with five percent choosing the Base sedan and the remaining 20 percent driving off in a Rio5 SX. Yet, based on the Rio5’s styling and the success of models like the five-door Mazda 3, we’re betting that the SX will eat up more than it’s share of the Rio pie.
