Having owned my V5 Bora for the last 6 odd months, I can safely say there is nothing wrong with the engine as a whole (so long as it's been looked after). MPG isn't all that bad on a normal run, it's when you put your foot down that it is a different story. Engine sounds nice too. Not going to be singing bells and whistles if it's speed you want but there's enough power there for an everyday car.
V5s are cruisers anyway.
