The 2005 Model was Better
I bought my 2013 Tucson not paying close attention to the details because I figured I was buying a nicer looking version of my 2005. WRONG!! The rear hatch had a window that could be opened. Not the 2013. The wheel covers went from thick and nice to the cheap flimsy material. Don't get me started on the 2013's seats. The material has something wrong where every time water is spilled, it looks like oil. I had the dealership detail the stains out twice which was above and beyond their responsibility (Curry Hyundai in Cortlandt Manor, NY). I have spoken to other Hyundai owners who experienced the same issue. Another thing taken away in the 2013 was the roof rack, which was standard on the 2005 base model. I was informed that if I do not buy a feature package, a roof rack cannot be installed, even by Hyundai technicians or the warranty is null and void. I can only guess that the roof must be flimsy.
As far as the engine and systems go, brakes wore out quickly in both years' cars but the engine runs great and I love the overall quality of the Hyundai engine. I would buy another base model Tucson ONLY if the seats are made of a different material.
