That was never the problem. The insurance didnt take it. The assessor classified it as being economically irrepairable, but the car was repaired anyway on the cheap but because the assessor wasnt involved, he wouldnt unblock the registration certificate. No amount of money would change that.
As for the engine, maybe it wasnt a proper GTD engine, but it worked one way or another. I never did get the engine number off it in the end, so I suppose that remains a mystery.
