RE: Is it worth it?
It is nice to have something like what you are looking to do, and I applaud you for the effort, however, do you plan on running it? You might find that after you put all this into building such a vehicle, you won't run it, you will sit it on a shelf and look at it. I did the same think, I build an all aluminum/titanium car. Spent about the same amount of money as what you are talking and it became a nice "show car" however I ran it 1 time. I ended up selling the car on ebay for $500. because I was had no use for it. I know it is nice to build something like that, but for what you are willing to spend on building the vehicle, do what the last post said, and hech for that much money, build 2.
Good luck[sm=thumbup.gif]
