You are paying for the "Limited Edition" and badging that comes with a Hennessey car....but it may help with the resale value compared to a car that was done at any old performance shop. The 550 package though really isn't anything more than a supercharger of choice bolted on with a tune. If my memory serves me right it does not include a CAI or headers+exhaust. I believe that is the 600 package....if I was going with a Hennessey package, the 600 would be the way to go...then get suspensions mods done locally afterwards.
