My view on whoever bought 1.8 is more practical and budget concern. It is wise choice considering no big difference except different engine but 1.8 is powerful enough.

In fact i bought 1.5t when i see 1.8 on the road driving side by side with me, i feel they are more worthy with the price they've paid and they don't need to worry with the new issues popping out for 1.5 turbo engine and maintenance etcs.

The only issue that i had is when the car on idling or stopped, it is vibrating but very minor that i can feel it.
I suspect there is loose hose that cause it, but when check with SC, they claimed it is normal for this civic, again it come back to QC of Honda Malaysia, as for consumer like us, no choice have to keep complaining to SC since it has 5 years warranty - problem is they normally will push away the small issues if they can that ended up you will bear with the small issues until it become big problem then only they will get it solved for you.

The biggest challenge is after 5 years which is no warranty covered, it will cost a lot to maintain 1.5t civic. I will choose 1.8 if i wanna drive it for 10 years. 1.5T civic i probably will sell if after 5 years depends on its reliability.
