I bought a GTI but drove a Mazda3 b4 I made my decision. The 3 is anemic in power and struggles to get any kind of speed. Also, it was creaking and moaning in the turns and made me feel like it was going to fal apart. Mind you, this is a brand new car.
Also, 5 door hatches dont do it for me at all. And remember, Ford is behind this car...so, make your bed where you want.
I dont regret my decision at all. I love my GTI.
