I'm considering buying a used diesel Grand Cherokee with a budget of around 150,000. My budget is limited, and as a working-class individual, I'm considering diesel for its fuel efficiency. I'm currently driving a 2.0T Mondeo, and the fuel consumption for commuting is 11 liters per 100 km. My concern is that some people say diesel engines are unstable and have high maintenance costs later on. My driving scenario is mainly commuting to work, with a daily round trip of 20 km. I’m also thinking about long-distance travel with my family during holidays. I’d love to hear from actual owners about their experiences and what I should pay attention to when making a choice. Thank you very much.
