I know your decision is made and I agree "no" is right (in my humble opinion)
For me there are two main elements if I was considering it 1) Cost - and probably that would end it for me! and 2) Availability - what you going to do at the top of Shap (or almost anywhere else) when you get a stone through the rad or a hose fails (how about including our own little Achilles heel, the metal pipe on the FIRE engine?) Bet it happens late at night and it'll be raining or snowing too! A 2 liter pop bottle full of ready mixed standard antifreeze in the boot always goes with me on long journeys.
