I wouldn't trust anything Hennessy sells. A while back a Hennesy Viper not unlike this one got creamed at the track by some modded Supra TT. It should have won easily (on paper). So this (much like the whole 99 Cobra incident) sparked some interest with car mags. They got a hold of a hennesy viper and found that all the performance specs were bogus. A bunch of Hennessy owners sued. It was a big controversy.
