John now has a proper V8 shell - from the protoype/development car 005. (This car is interesting in the fact that it never really turned a wheel, as it was built and then used as a classroom training vehicle). See here:
As mentioned he also has a written off 260 Tourer, which should provide most of the required parts including the authentic drivetrain.
I wish John every success with his venture and really look forward to seeing the results of his efforts.
