When driving the Cobra in the rain it's alright if you're driving into the rain, as it goes over the top of your head.
Different story if you're driving with the weather; you get wetter than a wet thing in water.
But even when driving into the rain it tracks around the edge of the windscreen, down your leg, and fills your boot.
I remember driving through the Awakino Gorge in rain some years back, stopped to gas up at Otorohonga, got out of the car on the forecourt, took my boot off, and poured the water out.
The forecourt attendant took one look at this unsmiling long-haired leather-clad hot-rodder, clapped her hand over her mouth, and headed for the back of the shop with her shoulders shaking.
The lengths I go to to amuse people.

I just went back and reread your whole thread.
You've done a bloody magnificent job in building this.
Sir: I salute you.

(So...how did the budget finally look?)
