Aye, but how far behind could a Solstice be really? I'd bet it's right there with the MX-5 in terms of handling.
Between the two cars, things are generally
close between them under most circumstances, but the Solstice ends up falling short most times because of its higher weight and the shoddy output of the ECOTEC 2.4L engine. Simply put, the dynamics of the MX-5 are superior in every way, and the MZR 2.0L was otherwise the cherry on top of the sundae. Sure, the handling matches up, but the Solstice just wasn't as much fun to drive, which is why it lost out to the MX5 in almost every comparison test.
The addition of the 2.0L Turbo on the GXP helped things quite a bit, both it and the Sky Red Line hold quite a bit of credibility as top-notch, affordable sports cars, but lets not kid ourselves... Its still not a 370Z or an S2000.
RE: Driveability, Useability, Liveability
Meh. I think you guys are making a bigger deal out of it than it needs to be. Drive them both, figure out which interior is more comfortable, more useable, and what you could see yourself not hating as much in the not-so-distant future. The snow and ice in Illinois is bad, not as bad as what we have here in West Michigan mind you, but certainly something that must be taken into consideration. As Joey has pointed out, there are plenty of crazies in Michigan that drive their MX-5's and S2000's year-round without much trouble... But that doesn't make it a good idea. I'd be more concerned with how much stuff I can fit in the trunk, or how many cubby holes there are to stash my Pre, iPod and Netbook when I'm traveling. Furthermore, I'd start worrying about where my feet sit when I'm cruising around, or where my arms will sit when traveling from place-to-place. Based solely on short seat times in the AP2 and the NC MX-5, the Mazda takes those criteria without much of a problem.
No, the NC isn't as macho as the S2000, but I think its the more-rational choice at the very least. The same can be said for the NB, which I love to pieces as well. I like the S2000, don't get me wrong, but even as I myself consider looking at one to replace the Celica, I know and understand its shortcomings... And those may not be things I'm willing to put up with.
