The Mahindra XUV700 has recently been replaced by its facelift, the XUV 7XO. However, while it is an excellent SUV, in your budget of Rs 15 lakh, you will only get a base model. Similarly, in the lower segment, you will be limited to low or mid-range models of the Kia Seltos and Tata Sierra. However, if you are okay with that, both are excellent SUVs.
The Tata Sierra excels in space and comfort, while the Kia Seltos is the better all-rounder, with punchier engines and more features. For your usage, we recommend the turbo-petrol automatic variant of either car, as it offers a good blend of price, performance, and refinement between city and highway use.
