Wow, you got your test drive the same day I did! I went by my local Mazda today and they had maybe 5 of the hatch and three of the i-sedans. From the pictures online, I was thinking sedan, but in person, I liked the hatch styling much better. I test drove both styles and I'm not really a car enthusiast or anything, but they both felt plenty peppy.
I wasn't as impressed with the interior as you were. I sure wished it had the lighted "wheel" controls for the AC like the Europeans have. I just wasn't as impressed, mabe because my current car is an Accord. Maybe it's impressive for the compact segment then.
Anyway, It's definitely one of the nicest looking small cars in that price range. But, as I'm a Hot Deals kind of guy, I just don't know about going for it without any incentives, especially with all the other great incentives out there. And the first model year thing makes me hesitate too.
Overall, I liked it, but it didn't make me so excited that I signed on the dotted line today...but I'm definitely not ruling it out.
