Hennessey doesn't have the best reputation among the Viper crowd where they started out. They even have a term for getting burned by John in the Viper community, Hennescrewed. I can't believe they are still around but then again there is a new sucker born every day. He is a great PR guy though, have to give him that. Almost any hot new car/truck that comes out and he instantly has one that makes way more power (supposedly) so his name is in the news again.
