Who's saying anything about more interior space? It already offers more usable space than anything else similar (Fit, Accent, Rio, Versa, Yaris, etc.)
I'm sure the 2.0L is just fine, but I'd like to see the new 2.0L they've put in the Forte instead. And if anything, its wheels are too big. The 16" that come with the 2u are perfect for this size.
The only things I'd like to see are telescopic steering and AWD as an option. Other than that, I don't see anything else missing.
