R8's aren't all that impressive except for how they look. Then again, this car was a spyder, much heavier than its coupe counterpart. But I do see the OP's main point of diminishing returns. My good friend with the R8 V10 said something along the same lines too.
My dream supercar to own one day will be the McLaren F1, Carrera GT or my very own bespoke car.
I beg to differ. My r8 v10 is insanely fast and will outhandle almosf any car on the road. This is coming from someone who's owned a gt3, modded m3, pdk carrera s and more.
