 I traded in a 2010 Santa Fe Limited FWD which was fully loaded for the 2013 GLS AWD.The car is a serious upgrade in every way.The external styling is much improved. The internal styling is also lovely, with much improved materials, backup camera and navigation system. The biggest improvement is in the overall ride and quietness.The previous model was quite noisy and you felt every imperfection in the road.This model is as quiet as a luxury sedan and goes over bumps very smoothly.Also, the previous model exhibited serious understeer when accelerating.This one does not, probably due to the AWD.So far, I'm getting better than advertised gas mileage.
