Instead of BRV, buy a Grande 2018/2019 under 10k KMs driven. It is the bestest vehicle you can purchase in this budget for a family of 3. You'll never regret your choice. Since you drive on long routes, grande will even offer you cruise control as well.
New Altis 1.6 is also a good option as advised by a senior member above, but it doesn't come with CVT, Cruise, paddle shifters, sunroof, DRLs, 1.8 Engine and a lot more. Grande having an ODO between 10k-20k KMs will be even better. Value for money!
