Mate! A very good morning! To be more precise and honest The Allion your referring to is a 1.5ltr engine. Just try the 1.8ltr engine where fuel economy is concerned. Rent it out if you don't believe me, you surely will feel the difference. Plus this 1500cc for an Allion is a made up propoganda by importers and other sheeps following it and spreading the word. So if your lucky, just do a search for a 1800cc. And they are cheaper than the 1500cc's. Do your math buddy, you know what I'm talking about. Hope it helped
Fuel Consumption - better than the 1500cc
Maintanence - same as the 1500cc
Resale Value - bit lower than the 1500cc
