Looking for any info on Gen 2 vipers with the Hennessey Venom 1000 twin turbo kit. I have an opportunity to buy a 2001 GTS with the venom 1000 tt kit. The car was built by Hennessey in 2001 and is still owned by the original owner. Does anyone know anything about these cars as far as how many were made and have any sold recently. I tried to get some info from Hennessey but they don’t have any records going back that far. What do you think the car is worth. What are the things to look for as far as issues with Gen 2s.
