If you are going for hybrid, get Prius C. Honda Insight's hybrid is inferior to Priuses'. Just make sure you find one with hybrid battery still under warranty or alrleady changed battery. As for master brake pump, yes it is prone to failure and repairing that cost a few k.

If you are not into car stuffs and just want something to drive around then new Axia is the way to go. No worry for the next 5 years.

However, do bear in mind the quality of both car is massively different.

Also, note that Prius C share some common parts with Vios. Not hard to find parts that are non inverter engine related.

Another tips...try joining Prius Facebook club Malaysia. Lots of owner selling there. Buy direct from owner instead of through used car dealers.
