Waste this piece of junk! I did the Hennessy upgrade to my ViperVan. If you want to know what that is check the 2000 Aston Martin V12 Vanquish forum topic "Caravan vs. Vanquish." Anyway My ViperVan would waste any Viper let alone a Hennessy so Screw You! It's for sale. I need money to start my new project.
