Are All axio's cvt?
No, but most imported are CVT.
and how many grades are in axio and their features
Mainly its X, G and Luxel.
X is 1.5 (1NZ-FE), all windows auto, keyless entry, retractable mirrors, headlight adjustment, ABS with EBD, no RPM gauge in instrument cluster.
G is 1.5 (1NZ-FE) as well with all the features of X but has a navigation unit, rear-view camera, indicators on side mirrors, better instrument cluster than X (has RPM gauge) and climate control as well. There are some limited versions as well which may have steering controls/push-start/immobiliser etc
Luxel is 1.8 (2ZR-FE) with all the features of G, FF alloys, steering controls, navigation, optitron instrument cluster and some may have wooden paneling as well
@mashriqain @cr33d anything you guys would like to add?
If i compare it with pkdm corolla 11th and 10th gen corolla which is better axio or pkdm corolla in comfort and drive
Comfort wise Axio is better, drive of Axio is better than XLi/GLi/1.6GLi auto/Altis auto. Referring to auto here because Axio CVT > GLi/Altis auto
what about resale of axio in sindh plus its spares are available?
Can't say about resale since I am here in RWP but spares are easily available though body parts might be expensive (when compared to PKDM corolla)
And a last question in how much i can get a 4.5 grade unreg axio with all that features eg: rpm auto ac nav multimedia steering etc with 1.5 and 1.8 l engine in khi? And what about its reliablity
That would be pretty expensive, since the only unreg axio you'll find will be 2011/2012 models. Check from @sharabhi maybe.
