Price of tube chassis?

I really enjoy building chassis, maybe you will too. Check out the U-weld kits from S&W Race Cars, Alston and Morrison. It's a lot of work but you'll save a lot of money doing it yourself. I've seen a lot of people get in over their heads, end up overwhelmed and then they sell the car cheap. Don't let that happen to you and what could otherwise be a nice car you can enjoy.
