You guys are right on the comments here.
1) The sport suspension isn't all that sporty. A number of guys (as Redroadster mentioned) are replacing the tall and soft springs for Mazdaspeed or Eibach (one and the same I'm told) springs . I intend to do this as soon as financially possible too for both aesthetic and performance reasons.

2) Discounts are available. When I got mine in December I was told that because it was so new, the sales manager I talked to could only discount the car a few hundred bucks. I made an offer based on a MUCH greater discount than that and he took it. The Miata / MX-5 never was and never will be a large-volume seller for Mazda.
3) Mazda apparently worked hand-in-hand with Michelin to develop the 205/45/17s Pilot Precedas for the MX-5. They're supposed to be an ideal compromise of comfort, performance and wear though they do take a bit of time to warm up I'm told. I can't really report on them yet since I've only just put them back on my car last night after having little 195-width snowboots on since December.
Benhaze, you mentioned you'd like to hear from people who own 'em. I've got one and wonder every time I drive it, why I didn't get a Miata years ago instead of wasting time with the Audi and BMW. This car makes me grin like an idiot every time I drive it. I love to rev it just to hear it. I love to imagine myself taking corners in Monaco everytime I hit an on-ramp. I love how it nips through traffic like a jack-russel terrior after a rodent. I love that it costs me less to lease, fuel and insure than my Audi did and provides me with more fun (and so far, reliability) than any of my previous cars.
