7500 km into the life of my car I saw the third trophy... It was a non-event to me, as I live in the flatlands and all I do is following big things in the slow lane (but always at a respectable distance).
Saving fuel became a bit of a hobby so I bumped up the tire pressure ( also improves cornering and sidewind resistance), dropped in LEDs and HIDs, taped some seams, blocked a grille, added some batteries to support the hybrid one... And last but not least replaced the awful meep-meep horn.
My lifetime average nears 55 mpg(US) or 70? Imp, my best trip economy is over 75 mpgUS 90Imp. Warm day with a storm wind aft.
Nonetheless, I do lose a leaf on my potty collection somedays, like last Tuesday when I got stuck in an accident jam, then ran with the pack when we got released. But I have to remember to look at it as other than the occasional frolic it always shows the same on key-off.
Don't let this put you off. It just goes to show the potentional this car has. You will find that driving in a fuel saving way will come naturally over time, even without trying.
In my case the hybrid battery was lazy, when I bought it, just 2500 km on the odo but having sat in a lot for months. It came back to life in a few months, up to full capacity in the summer.
