Mine is 2010 also but American version and without 3rd row. It should be possible to have a 3rd row installed but I doubt that can be done here.
I'm thinking to spend around 750,000, so I'm afraid prado and highlander are out of the question, really like Highlander though.
Third row was discontinued in 2010 (customer complaints...not enough space) and is now only available on the Santa Fe Sport.
750,000 pesos or about $17,000 will have you reaching back for older versions of the Pilot, Odyssey or Sienna.
If you desire SUV qualities, the Pilot fits the bill. For sheer roominess, the Odyssey or the Sienna are also good choices. Just be aware that quality can vary between different years and the first year of a new style....always has bugs that need to be worked out.
When you narrow your year, make and model down, PM me and I will run it through my clients database that aggregates known problems, recalls, complaints, etc.....and then provides rankings for models within their respective categories.
