Up until fairly recently, most "carbon fiber" sports cars were, for the most part, structurally dependent on an aluminum sub frame. All of Ferrari's current lineup - the 458, 599, etc. - have metal frames, as does the Bugatti Veyron, the Lamborghini Murcielago and Gallardo, and so forth.
The McLaren F1 is, on the other hand, a fully carbon fiber vehicle, and several others - the Zonda, Enzo, and Koenigsegg in particular - come quite close. However, there are some important differences between bicycles and cars. Unlike the average featherweight road bicycle, these cars aren't structurally dependent upon the outer millimeter or two of carbon - attacking one with a boxcutter, for example, isn't likely to cause any serious damage. Furthermore, unlike a bicycle, these vehicles are mostly kept under a dust sheet in a garage - many McLarens have less miles on the odometer than some Cervelos.
That said, even these paragons of automotive engineering are vulnerable to the pitfalls of carbon fiber. An Enzo was recently totalled over damage that on a Civic or Taurus could be repaired by any body shop, and resurrecting the car required a complete replacement of the body.
There's also the issue long-term damage. The best examples of these are the featherweight Lotuses and TVRs, which are a far better analog to the construction techniques used in composite bikes. After thirty years, many of these cars are simply coming apart at the seams.
Nuances? This is a speaker with horrendous harmonic distortion at all frequencies, comb filtering galore, and severe roll-off at both high and low frequencies. It doesn't matter how you measure it - as an accurate transducer of electricity to sound, it's rubbish.
(Yeah, I roll my own.
