The bonnet

 I was never keen on the bonnet layout of the original design because if the bonnet flipped up while you were driving, the windscreen would hit you in the chest and the top of the bonnet would cut your fingers off on the steering wheel.

 I decided on a scuttle and removable centre while the nosecone would hinge forward at the front.

It was a nervous time cutting the bonnet. But with patience and going slowly the end result wasn't too bad.
