I agree with Dave, looks like its a one off and nicely done.
Definitely different than std CCX car for sure.
Value; Would need to be looked over to determine as glass cars are robust and the CCX frame had no way to support the alloy body. That said if done right it might be a nice car to have, still different than KMS or MKVI as look at the door hinges, welded directly to discrete door frame tubing, might be fragile in comparison to other alloy cars.
Would need to be seen in the flesh...... My $0.02
I will be in CA next week and could review in the flesh, also John Bessey could look it over.
Just PM "MB" and offered my services...
