My wife's 2010 was in for a.minor repair and she got a 2014 ES-350 as a loaner and the ride and feel was significantly better. I don't understand why. The weight is about the same, the wheelbase is close yet it has a more solid ride, feel and better handling. Additionally, it is a lot quieter and there is a lot less of the "feel of the road" through the steering wheel. I liked the loaner so much that I am going to contact the loan car manager to see if she will sell it. Can anyone account for the significant differences ? Thanks
