I thought I was asking a narrow and somewhat comparative thing like body stiffness and body flexing when driving in a spirited way or over bumpy roads when on the street. Do you have an R8 as well?
body stiffness and rigidity is far superior on the R8. it's 25 years newer with vastly more modern components. there is no comparison between the two cars.
i don't personally own one, but i have driven my 2002 NSX and Audi R8's of both engine configurations on the same day countless times. and have spent many, many miles on road and track with the R8. it is a magnificent car, and i would buy an old V8 manual in a heartbeat...
1. The NSX has a more exotic driving position due to its noticeably lower cowl. Relatively speaking the R8 feels like you're sitting in a hole.
2. The NSX manual steering rack provides superior road feel. Many describe the R8 steering as being somewhat "numb".
3. The NSX weighs far less than the heavy R8, making it feel more nimble and tossable.
4. The NSX is likely more reliable and cheaper to maintain.
5. The NSX is rarer and more historically significant, making it likely to hold its value better.
As good as the original R8 is, there was nothing groundbreaking about it.
relatively speaking, this is only your opinion, not mine or most others. i could argue some of your points above, but i'm in Hawaii and have better stuff to do.
simple fact of the matter, the R8 is a much more modern car, and significantly better in every way. that's what a quarter century of engineering will do for an automobile.
if you think an NSX compares to an R8 in any measure of performance, you are simply dreaming. a V8 R8 will simply run away from an old NSX and disappear, the V10 even more so.
the first generation R8 doesn't need to be ground breaking, it's an incredible car. it carried on where the old NSX left off and then some. it also easily outsold the original NSX by 1/3 more cars in 1/3 less time. you do the math.
many previous NSX owners and Prime members have also previously or still do own R8's, so there's another testament to the car, not that it needs it...
p.s. in L.A. where i live, i see other NSX's fairly often. i also see 458's, various Lamborghini's and R8's daily. 911's and Prius' are driven by 90% of the population of southern California, but that's entirely another story.
