whats the difference between Premio and Allion, specs engine etc?? anyone (premio allion owners) have a clue? i have heard that Allion is a low end version of premio but looks more dashing that later, is that true? plus i have seen allion with A15 emblem on its back and some with A18... does this mean that Allion is available in 1.5 & 1.8 liter engines?
