Fair dues, I wasn't aiming my post at anyone in particular. Just amuses me to see people caring about the costs of fuel when driving a car of our type.
I don't like driving on motorways full stop though tbh. I more often than not try and find more driver friendly routes. I drove to Cardiff from Manchester the other evening, the only time I spent on a motorway was half an hour on the M56. Great drive and loved every minute, cost me a relative fortune but I couldn't have cared less ...
