Rowing Guy, Right now the cheapest way is a simple three step process.
Step #1- Ship car to Piranha Brothers garage.
#2- Pay $ 12,500 [approx.]
#3- Drive fast and take chances!
Nothing cheap about this swap. It would be a custom build.
Let me know if your interested. We are currently scheduling for summer 2015.
Thanks for the interest, Dinsdale Piranha
