im not saying one is better than other
i dont have extended experiacne with new corolla's per yahan log kehte hain ke its more tuogh and takes more abuse than civic's which is fragile on the other hand.
as i dont extened experaice with corolla so i cant tell on my own tht is it tough or not but with my personal expericane civic has sustained all the abuse we have done to it without a hitch and has done alot better than old shape corolla.
so im not in the position to directly compare GLI suspension with civic's but i can tell that overall expericane of driving the civic is better.
many ppl say this as well that corolla ke suspension high hai aur soft hai ie its better but i like the more responsive suspension of civic. go change lanes fast and civic will give u much more secure feel of the road and much more confidance in the ride in my oppionin ( with the exception of my limited expericane with new corolla)
