there is no requirement for heaters as far as I know, its definitely not in the MOT anyway. Weather there is a 'law' for it is another matter, ive never had a problem on the many occasions ive been stopped...
Why would you need to faff still sat in the seat, it takes 30 seconds to safely pull over, wipe it off and put the harness back on. Either way, Ive tended to not drive it when its raining at all over the summer, it was never meant for winter as said.
I wasn't actually referring to the heaters being half arsed, i was just referring to everyone who removes the rear bench and goes 'my cars stripped', because simply its not!
As for dashboard not being needed, I dont see why, as its really literally not in my case. I have two switches in the whole car, no heater controls or cd player so there is no purpose for it being there....not to mention it wouldn't fit with the cage in anyway, the bulkhead bar is in the way.
