I think this is pure genius
I had a look on ebay and saw there were about 2 suitable Sierra donors and hundreds of MX5's. I understand they have great engines and boxes in them so if it can be made to work then this absolutely has to be a winner. Given the quality of Andy's stuff this has to be good news for the roadster. I wish you the very best with this venture which I am sure will be up to your usual high standards and sure as hell makes sense from a commercial point of view.
Bloody good stuff, I say
Dave.
