Yup probably thats the reason they are offering the MT altis for only 30k more, If u goto convert ur gli to altis in looks the figure goes like this.
-Alloys rims (20k each in case of genuine) 20k for 4 in case of copy.
-Side skirts (5k).
-Door mouldings (3k).
-12 pcs paint (10k) (4 door handles, 2 mudflaps, 2 side skirts, 4 door mouldings).
-Wooden Paneling 7k (genuine) 3k Copy.
-Side mirrors retract (8k)
-Fog lamps DEPO (6.5k)
Rain sensors arnt going to be avalible easily.
So even if calculate costs for copied stuff, exterior modification is off about 45k wooden paneling 3k and side mirror retracts 8k which makes it off about 55k all in all.
So its pretty much okay, as u get a airbag. Plus a better sound system, OEM alloys which cost 20k each. Gear knob, A better arm rest, and not to forget the Optiron meter.
And i guess i read some where maybe in the slide show there offering a automatic sunshade for the rear windsheild as well, maybe thats with the SR model.
