Haha! I can see your point about the Paramedic and who they may have been going to help... let's just say I have to deal with those sorts of people sometimes (see my comments about the GYs in my original post!).
Funny you should say that about the C Class... stuck on a hill on the A134 this morning, were a Jag XF, a BMW Z4 and a C Class! All that money and they can't handle a slight hill! However, if I was given one of those said cars, I wouldn't complain too much!
Many thanks for the mileage/XL info on the Uniroyals... they will be top of my list if the GY's turn out to be rubbish...
All the best, Tony.
