I've also bought the two door Mira 2007, manual. The engine is the 250 LV one. For the first two hundred miles I've gotten a fuel economy of 14.5 km's per liter, the heater was on for most of the time though. Slightly disappointed with it to be honest, however, i'm hoping that the fuel economy will improve after some tuning. I'll post the mileage again after the tank empties!
btw, do the 2006 and 2007 models have the same engines?
