We had a Leon Cupra and were using 40-50 quid a week in petrol. We now have a Focus Tdci and it only use's 20 quid. When i want to hear a nice exhaust note and go fast i get on the bike.
Don't really miss petrol TBH. Since i got the bike i've never been bothered about driving fast in the car. its just a way to get to work that's it really.
