Be careful of buying used Viper's from "non-friendly" Dodge dealerships. There are some great dealers in this part of the country.
Try and buy something that has an extended warranty, or at least one that you can still purchase a warranty for.
Make sure you have a Top Viper Tech go over the car before you purchase.
Join the VCA. There is no better way to get questions answered than through your local club.
Good luck. You are about to start living life.
