The plus points of Civic X are looks, Bullet proof and reliable R18 and CVT (BTW Honda Prosmatec is a horrible transmission). Grande have overall better build quality, excellent suspension very less known issues.
Grande have very refined CVT however it's maintenance is critical and difficult. Toyota ZR engines are in PKDM since quite sometime but many issues reported on PW and internationally as well mostly regarding VVT rattle and oil consumption. Which could be due to wrong grade oil usage.
As a practical ride I would prefer grande over civic on any given day, If we particularly compares engines, than nothing in PKDM can beats R18 in 1.8 category in terms of reliability, robustness and tolerance for abuse.
Anyways apologies for irrelevent post, It's Elantra Thread, don't want to spoil fun for PW fellows.
