What luxury? The Z06 is not luxurious in the slightest.
Agreed.
In the somewhat reasonable/affordable price range the GT-R takes the cake.
I'd get the R8 instead as well.
How was the car a disappointment? It was highly lauded by virtually every single member of the automotive world, not to mention all the fanboys.
Back to the original question though. I'd have to agree with the Veyron.
There is no other car with such a level of refinement, performance, spectacle, exclusivity, and notoriety.
