Over 3 years though, that's 10k. It would probably be half that in a diesel-wagon.
What comparable diesel would average 53mpg required to halve his fuel bill? Certainly not the 2.2 TDCi. He would need to be looking at far smaller cars which isn't really comparable.

Motorways are boring whether you're doing 70 or 120MPH so I tend to just sit back and relax in stress-free fuel-saving comfort.
