Honestly I would just lose this idea, insure my NSX and keep tracking it if I were you. Nothing else will be as fun and as long as you are covered... who cares. Plus you get to master your real car. A second car isn't just the car... its the storage, the insurance, the transport, the maintenance, the taxes, the things you have to go out and fix... this is what the NSX was designed to do. Go on a track. And not to sound like yours is not valuable but it isn't a 2000 mile Zanardi or a 2005 one owner Imola. Just drive it and enjoy it man, stop worrying. Life is short. I really mean that. Life truly is short... don't get too attached to objects. An experience is always more valuable.
