Since your usage isn't particularly high, a petrol automatic would make sense. Not only will it be more refined than a diesel, but also be more affordable to purchase. Within your budget, there are plenty of options, with naturally aspirated and turbocharged engines and CVT, DCT, AMT and torque converter automatic gearbox options.
If you want a well-rounded SUV, the Mahindra XUV 3XO is the one to go for. It's got a spacious cabin, it comes loaded with features, and there are two petrol options as well. However, if you enjoy driving, you'll find good value in the Skoda Kylaq.
