Most reliable daily drive with lowest TCO

Need advice on a new daily drive.

I currently own an Alterra and a 9-year old Vios with almost 200km on its odometer. My Vios is my daily drive, and the SUV is used only during long trips and coding. I would replace my Vios soon with an equally economical car (in terms of TCO and fuel efficiency) - After 9 years of ownership, the only major fixes done to the Vios are compressor replacements and the normal wear-and-tear maintenance (e.g. brakes, suspension).

There are too many choices in the market right now, and I'm torn among the small cars (Wigo, Mirage, ...), subcompacts(City, Vios, ...) and mpvs (Avanza, Ertiga, ...).

My criteria:
1. I don't need a high performance car.
2. I need a car that I can own convenienty for the next 10 years.
3. Low TCO and fuel efficiency. Cheap parts and maintenance.
4. Basic security features (sensors and airbags).
5. Flood-wading capability is not that important.
6. Budget of 500k - 900k.
7. Manual transmission, but light to drive (soft clutch).
8. Best discount for cash buyer.
9. I don't go for looks (evident on my "hearse"-looking Alterra as the haters say it). I go for reliability.

TIA :)
