We would recommend you go for the recently launched Mahindra XUV 7XO. Although your running is not that high, we would still recommend you choose the diesel variant as the petrol engine, though silky smooth and powerful, is not very fuel efficient. And considering half your driving is on the highway, there is an unlikely chance of facing any DPF-related issues with the diesel variant.
The diesel engine is also refined, and the 6-speed torque converter automatic is smooth and quick shifting, which makes city driving and highway overtakes effortless. In your budget, you can get the AX5 diesel AT, which is well-equipped.
