Hello, I currently drive a 2013 Hyundai Elantra that is loaded but I am not happy with the lack of engine power. I thought that I would eventually accept the 1,8 liter engine to save on gas but no. I have tested out a 2013 Mazda CX5 but think I would appreciate the 2.5 engine over the 2.0 so I would have to look at a 2014 or newer model. The question I have is the Touring model over the Grand Touring? I would love to have leather heated seats and navigation but I read a lot of negative comments on the navigation systems in these vehicles. Is the Grand Touring worth the extra money? You also get larger tires on the GT but is it worth it? I think 17" tires are fine for me. Hate to give up on my Elantra so soon but just want more.
