Since your daily commute is as much as 70km, you should consider a diesel luxury SUV, and there are two good options in this price range. The BMW X3 is more engaging to drive, and since you have already owned a BMW car, you will likely be familiar with the brand's aftersales and service ecosystem, and could even talk to your dealership about a loyalty benefit.
However, overall, the better SUV is the Mercedes-Benz GLC. It offers a more luxurious cabin, rear seat space, and a comfortable ride. Plus, while not quite as engaging to drive as the BMW, it's still a lot of fun from behind the wheel.
