$25 for the NSX is asking for big costs later. I'm positive a $25 NSX has almost as twice the life and mileage of the Supra TT. The costs of performance or OEM NSX parts are expensive. The NSX can be maxxed out with a supercharger or turbo with only 9 psi and nearly 400 whp. More than this, the rebuild of internals is a must. It's failed so many times after this threshold.
The NSX is nicer to drive and unique. If you're not into high hp, then throw a set of 18" wheels on it and it'll be fun to drive. A simple body kit will make it turn heads even if you're the Ferrari crowd. For handling & look wise, the NSX has my vote.
