'Matching numbers' is not so relevant in the Honda-world. Based on the silly (and proven wrong) statement of Enzo Ferrari that aerodynamics is for people who are not capable to build engines (haha), one would say a 'matching number' certificate is only needed for the junk engines build in the F- and P-cars of that aera. Moreoverthis, such cars are bought by people having very little technical clue or two left hands, to round that prejudice off. No wonder, they jump after x certificates to justify that THEIR object of desire is the best available toy out there. Of course, there are plenty of false certificates and false cars out there for sure. Thanks goodness, that kind of uncessary 'industry' can't evolve in the NSX-market.
