That bonnet was useful once when I drove too fast into a flooded
roadway. I was able to open the bonnet, lift it, dry off the ignition
wires, and drop the bonnet down again, all without getting my feet wet.

My Herald often crapped out after going through a puddle ... must have
been where distributor or coil was situated ... can't remember now.

I remember the big luxury of fitting a stick on heated rear window
demister ... very flash at the time.
If I had that switched on at same time as headlights dynamo couldn't
keep up and battery slowly discharged.
