My long term average (3 years) is 4.85 l/100k, or about 20.6 km/litre. (Km/litre??? some sort of time warp involved there, I feel. In Australia we use litres per 100 km don't we?) - Hey, I've just realized - the bus I drive gets 20.6 l/100k - something freaky there!
I enjoy the power when I use it, but mostly only use the power I need. With any excess, there is always a "right-wrist tax" you must be prepared to pay.
