 The 5 Door KIA RIO SX is clearly the best car in its class and the driving experience can only be described as pure fun. There are other competitors in this class that are better in one or two areas, but none have the overall combination of a terrific enginewith an excellent 6 speed automatic transmission,lots of interior room, fantastic looks, an abundance of safety features, high tech gadgets, nimble handling, and the best warranty in the industry. The RIO is extremely comfortable on long trips, which is unusual for a small car. Can you believe the outside mirrors are heated electronically and fold into the car with the touch of a button? And it has a rear view camera!
