The idea of swapping over running gear to a second 'shell', the term "not really a car guy" and pizza delivery driver for a job lead me to believe this will be a huge task to accomplish. You should just sell the Xfi to me
I'm mostly joking, but if you don't really enjoy working on cars, you are not likely to have a good time with the Xfi or any car for that matter that needs a ton of work. Trust me on this, I've built several cars and modified the heck out of a few others. I've never paid myself back in the suposed labor costs savings. But I enjoy tinkering, re-engineering things, cutting welding, and machining parts.
