Thats nice of you to say
If you decide to run an X6 it's down to you how you want to do it, unfortuantly Woody I'm afraid you're not right, its more expensive to buy just the B4 bits you need as spares than a complete car, especially as you can flog the bits you don't need on t'ebay.
Whether you want to build it from a team or FT car is also a matter of personal choice. The stock steel turnbuckles in the team are junk and not having threaded bodies is less convinient but functinaly the rest is fine.
Chris is right though, look around, there will often be some well cheap 2nd hand B4's around. I seem to remember my last FT went for about £65 or something stupid
If you desice to get one, give Chris or myself a shout and we can give you any other advice you need. We'll be at the endurance race (team vintage), the rest of the regionals etc.
