With such a large price delta over the 407 and 350B3, it's hard to justify buying one for the performance improvements alone. They are fast, HIGE is better than the others, but HOGE lags behind the 350B3. Their DOCs are competitive if you believe what they publish.
I'm willing to bet it's the 500k USD base price delta that scares away most folks.
What do you guys think?
