just follow the official service schedule since its a new car, i think u can get it from proton website

most feedbacks on the car itself has been positive, u can have a look at the fb owner group

turbo lag is going to be evident on most small CC cars and tbh i dont mind it during my test drive

you can always downshift ahead of overtaking or merging to minimize it

at this price point, its already a better car than city/vios from A to Z

better nvh, better ride comfort, more features (well one can argue no android auto/apple carplay) and the list goes on

kasichan laaaa bro that gen of civic is literally the least desirable no matter what type r engine u put into it

shit chassis is shit, no good engine can save it
