well.....i have to say, that the MPG is a lot better than the vectra though you do have to fill up more often as the "tank" can only hold so much fluid.Tends to leak every now and then aswell......though when useing this vehicle you do tend to hold up traffic a wee bit..unlike the vectra where i just pass all the traffic. ;) Overall though, the air conditioning is better....there are no rattles that mean iminent stretch of the purse strings and much cheaper to repair.
