i own a GLI 2010 and ma cousion own a Civic Reborn 2010.... i have driven both of them on long routes.... GLI for more than 10,000 km and Reborn for 2,000 Kms............ i never got tired in ma GLI.. but i drove Reborn for short trip of 150 Kms and i was tired... its seats are really not comfortable.... i had the same feeling in my GLI but driving after 600 KMs... non-stop Lahore Islamabad and than back after 15 mints stay...... i am honda lover but Corolla is ahead in comfortability... Mitsui and Liana comes after reborn....
i never sat on Optra.. but heard that it is also very comfortable...
