Right, sometime back I was watching top gear episode on nsx and if I remember correctly they said that only 5 nsx-r were produced ever. Have you seen it?
I don't understand why production of cars like supra and nsx was stopped! May be cost was the reason, as said by @xulfiqar, but again what about price of cars like lfa, when prospective buyers can pay that much amount for same brand category then why not for these legends.
