for seating 5, gli is not a good idea, it will not return any economy at all, the 1.3 auto, is also a no show. a 2014-2016 altis 1.6 with 20k max will fit your budget well, there are ways to make it theft proof, its all together the best option. Now if resale isn't a a concern, you can probably land a clean 2014 grande with about 50k on the odo, that would be an even better option.
As for brv, its a practical vehicle if you like to carry to 6 people often, and in its price, its good value for money, but as with all new things, it will take some time to capture the market, but it is increasing in numbers on a daily basis, thanks to toyotas long waiting period.
