i voted the NSX's again.. i like it more, since it's "Honda DAY".. So more than one honda car is more like it. However.. in terms of "HONDA day", the S2000 should win because the NSX is technically under Acura..
HOWEVER again, both cars are sponsored by another company..
I think the definite win would be a pair of S2000 Vtec's that are the road car themself, no race car formation
