Since you are accustomed to the reliability that Maruti Suzuki offers, it's best that you stick with a Maruti SUV for your next purchase. Given your budget and requirements, your best bet is the Maruti Suzuki Brezza, the ZXi+ AT variant, which is a fully loaded spec well within your budget. The compact SUV is spacious and comfortable for a family, while compact enough to tackle Bengaluru traffic, with a smooth 6-speed torque converter automatic to give your left foot a break. It's also potent enough and stable for use on short highway drives.
Alternatively, you could choose the more compact Maruti Fronx, which comes with a punchier 1.0-litre turbo-petrol engine, but it isn't quite as spacious or SUV-like as the Brezza, in case that is a higher priority.
