An economical reliable daily drive for about 700T...best bet is a subcompact sedan. AT most likely because you are in MM.
Honda City or Toyota Vios ,its your choice really but this can help:

Need bigger space, the Avanza 1.3 J is within range.
The Lancer that you mention is already in another category being a compact sedan. Its 1.6L engine is more powerful but with it comes more fuel consumption. But it's one of the cheapest compared to the base models of the Altis and Civics.
I don't know if you're warm to a 1.3 AT Toyota Vios. Judging by sales, a lot of people could not be wrong.
On car entertainment, just get an aftermarket DVD system with LCD headrest monitors.
