the nsx might not be that powerful, or that exotic...but just because it doesnt have a lot of hp doesnt mean it isnt that fast...a viper may have 400hp but it is heavier and it does it buy pure power...the nsx on the other hand has a lot of technology put into it...the capabuilities of the nsx are huge and the reliabuility is what you would expect from honda...
something to think about
nsx-r: 1/4 mi 12.8
new viper: 1/4 mi 12.37
dont forget that the new viper has a 500hp v10 while the nsx has a 290hp v6...is hp everything? definatly not
