retractable mirrors have motor inside it, otherwise mirrors are same,
since it has been introduced in altis 2011 ownwards, so u would rather need to spend more on the mirror, since its still new
when i came to forum i was also like u, i wanted to change GLI into Altis, but when i started to work upon it, it will cost u same as if u buy a altis
and at the end guess what happened
i bought Altis and sold GLI
