Ive got both the cars, Glis, 10th Gen in every aspect is better then the 9th Gen models.
leg space (rear and front)
Steering wheel
Visiblitiy
Seating
Audio
looks
Comfort level
Low cabin noise
bigger boot
-bigger wheels/tires (same size as of Altis now) 9th Gen Gli has 175-65-14 while Altis had 185-65r14.
Much more road gripier then then the 9th Gen (yes civics are still better)
Bigger bumpers (safety)
etc etc, To cut it short, 10th Gen doesnt looks too but is alot better then the 9th Gen
I feel the A/c of the 9th Gen is better but prone to coil leakeage.
i feel the 9th Gen accelerates better.
