My view on the above topic is both Allion 260 and 240 (2005) are better than Axio. I have driven both the Allion models & Axio and prefer the Allion models. BTW Axio G has lot of options and as a result the price is higher than X.
Allion 2002/3 models are older now and If you are searching for an Allion try to find 2005 and above with beige interior, flower lights, Illumination dash etc;. Maroon and Wine red colors are fast moving and very difficult to find. If budget permits go for Allion 260 which is a superb car.
