2009 Toyota Altis 1.6G AT for 550k? Good Buy or Not?

Hi im planning to buy a toyota altis 2009 1.6G, checked the car earlier ok naman siya.

Check its engine and i saw nothing suspicious naman.
Markings on the screws are still aligned with the machine.
17inches na din mags.
Ok naman ang aesthetics overall and pati interior
Seats are leathered na din
ODO reading is at 35k

Though:
Hindi siya casa maintained, seller told me that after the 2 years warranty from the casa they skipped the regular maintenance na.


Overall ok naman siya, did i missed out something na dapat ko icheck? is this a good buy for 550k?

Thanks
