No offense but I dont love the design. And moreover, it is less powerful than previous Avanza. Previously it was 107hp & 141Nm. Now it's 103hp & 136Nm. Correct me if I'm wrong.. 

Yes. The styling of the kit is no doubt wild and sporty. However, I don't like it since it looks bulky as there is some mental Toyota engineer paste some plastic on the bumper, making it looks wider and thinking that it looks great. Furthermore, I'm the kind of person that thinks 'fast looking car need to be backed up', you know what I mean right? Hehe.
But there are things I do like and think that it balance my upset on the design, a little. It's the little2 things: Electric Wing Mirror with Signal lamp, Grip door handle, Second row seat now can slide, Beautiful dashboard, Cool center console box and Button-ised Steering. Most of all, Toyota know that uncles and aunties love black-trimmed interior too..

I haven't seen the Prado.
Anyway, I guess that's it. I can only comment on the design and spec sheet for now. Yup. The side mirror is not retractable. But at least it got signal lamp there. And if you see nowadays that is trending on most new cars. Maybe I'll change my side mirror, for a reasonable price, of course. 
About the driving experience of the all new Avanza, I'm very sorry. Never driven it before.
