So.. Ditching the NSX and the Mazda racecar and hoping ONE car can fill both needs? won't happen.

The Mazda has jadded you towards extremely light weight and incredible handling. The boxster, NSX etc are fantastic for street cars but they are not racecars. You will find that out on your first aggressive track day. Too much body lean. Too much brake dive. Limited alignment settings that destroy the outside edges of tires. SO.. now your 1 car will slip down the track slope. Aftermarket springs and shocks (unless you get PASM). Then camber plates and/or 997 cup lower control arms. Now you've thrown another $4-6k just to get the handling "right" for your car.

You mention concern about warrantly and voiding it when you track it. So, i say, get a plastic windowed "S". Why? less money. Plus, you can then worry about paying for explicit DE/Track insurance (figure severl K/year plus a 5-10K deductible) so why wad up a new, more expensive car to begin with?

I've seen 250hp Boxster S's keep right up with, or lead, 993's, 996's (even GT-3s) etc. After all, it depends more on the driver in many cases, not the car.
