Purchase advice Discovery Sport Si4 – Experience with the gasoline engine?

Hello, I am interested in a Land Rover Discovery Sport Si4, which I recently visited. It is a model from April 2016 with 140,000 km of mileage and an output of 240 hp. I wanted to ask myself how reliable the gasoline engines of this series are. Are there known weak points or typical problems, to which one should pay particular attention? Are there experience values in terms of mileage, maintenance costs or possible engine problems? The test drive was good overall. The chassis made a solid impression, and the gearbox also switched smoothly. Nevertheless, I want to make sure that I don’t miss anything when I buy it. Has someone from the community already gained experience with this model or can give me tips on what to pay special attention to? Thank you in advance for your feedback! Best regards, Darko
