Well, Luckyj I think you are refering to allion 260 but you won't get one in your price range (max 3.3M) a descent one would cost around 3.8 M. But on the other hand a 2007 allion 240 anniversary models would be available (but hard to find) within your range. 240 is not as good as 260 on fuel as well.
The other two cars ,axio & civic(registered ) are within your price range. I personally own an axio and it is true that it is good on fuel, but i'm not happy with handling of it in high speeds. If you buy one make sure to find a G grade which has lot more options than X (which doesn't have even a RPM meter) and there won't be much price difference as you buy them brand new. Civic is spacious than axio and comfortable too. But fuel economy is not as good as axio.
I suggest you buy a good and spacious sedan like allion,axio or civic than buying an aqua. They might be 7-8 years old but they are trustworthy if you find a decently used one.
