I managed 57.2MPG in my Firefly over the last week
I finally got to take the slow road, and do P&G and EOC. And not have any breakdowns, for two round trips(512Km) the new route is so quiet that I only get overtaken like once or twice a trip. and i'm usually doing 10-20km/h under the limit. A few more ecomods, and no sleeping in and I should be in the top 10
