While there's never a good time to buy cars -- cause newer, nicer and better cars keep coming out. I feel it is especially true between 2017 to 2019 (I feel).
Reason being is that other countries already have adaptive cruise control, autonomous braking, and even auto pilot.
Here on the full spec or high end cars you get blind spot detection, cross traffic alert, reverse camera etc. But it's sad when a full spec Civic in Malaysia is just the poverty pack in USA.
