Though the Kia Rio and Rio5 are ripe for a major overhaul, they remain a sure bet for the automaker, and even for the owners. The 2010 models come with several aesthetic tweaks, among them a standard cruise control, and a fuel economy indicator. These cars are still powered by the very reliable 110 horsepower 1.6-litre four-cylinder engine, offered with either a five-speed manual or four-speed automatic transmission.
