Certainly bigger than 60l, even the Cav was 69 litres. I can pay more than £60 to fill up - at 92p/l, so I'm guessing closer to 80l.
Was interesting lately - normally get a FC reading of 300-310 miles for a full tank, this is with 2 mile trips to the supermarket and daily 8 mile trips each way dual carriageway driving to work. Went up to Scotland recently, stopped to refill in Fort William (after some 300 miles on the motorway - 1 stop, and 2-3 miles town travel to get onto motorway) - FC came back with 512 miles. I could have kissed the miggy. Quite a graphic demonstration to me how poor the miggy is around town, and how unsuited to my day-to-day life. But while I can afford it, I'm not swapping her for anything.
