Back to the original question: longevity of the Voodoo. The GT350 I drove at the Track Attack last month in Charlotte had 16,000 hard track miles on it and the engine (2017 model year) ran like my 2020 HEP. That says a lot. Some other cars used at Track Attack had even more miles.
I hestitated buying a GT 350 in 2019 because I couldn't justify spending that much for a weekend car. I bought a PP2 instead. After one year, I traded the PP2 in on a 2020 HEP. I spent more than if I bought a GT 350 in the first place. You won't regret the expense.
