BMW X3 xDrive20d M Sport Diesel

Since you are looking for a bigger SUV than the Hyundai Creta, you can consider the BMW X3 and the Mercedes-Benz GLC. Since you mentioned you do not often get a chance to drive, we would recommend the Mercedes-Benz GLC over the BMW X3. 

It has a more comfortable back seat, the interior feels more plush, and it has a better ride quality than the others. That said, whenever you do get a chance to take the wheel, it is very enjoyable to drive, with strong performance from both the petrol and diesel engines.

You should check out a luxury SUV such as the Mercedes-Benz GLC or BMW X3, which will feel like a good upgrade to your Toyota Fortuner. They might not be as large, but given that your driving is in the city, this shouldn't be too much of a problem. They have sophisticated and refined petrol and diesel engine options, high-quality cabins and lots of features. 

Plus, they will be considerably more comfortable and easier to drive than the Fortuner. If you simply must have more space and size than the Fortuner, then consider the MG Majestor, which will be launching very soon. 

It's unclear how much you will get in exchange for your Fortuner, but assuming it is not too old, big Toyotas tend to hold their value well, so these SUVs should fit in your budget.

35,000 kms is not a very high mileage at all, for any car. So if the car is running fine and you are happy with its performance, we would not recommend selling it purely based on its mileage covered. 

However, if you are still keen on a change to a newer car, you could look at the new Mercedes GLC or the BMW X3. 

Without knowing your exact requirements, it’s hard to suggest one outright. Among the options you’ve listed, the BMW X3 is the newest and offers the most features, though it’s also the most expensive. The Land Rover Discovery Sport has the advantage of a third row of seats, though it’s best suited for children. The BMW X1 will be the easiest to drive in the city. The next-gen Audi Q5 is still some time away, with its launch expected around 2026. The Jeep Meridian, meanwhile, won’t feel as premium or as refined as the other options you’ve mentioned.

In your budget, it's best to go for the BMW X3, although you might have to stretch by Rs 2-3 lakh. It is the newest SUV, offering a strong 2.0-litre diesel engine, plus the latest tech and a spacious and comfortable cabin. The Discovery Sport is a capable car, but it is quite old now and its age shows; if you need a third row of seats, however, do consider it. The X1, in comparison, is a segment below and offers less powerful engines and, of course, less space. The new Audi Q5 launch is some time away, and while it is capable, note that it will only come in petrol guise, not diesel. You could also consider the Mercedes-Benz GLC, whose 2.0-litre diesel is also strong, and it offers a spacious and luxurious cabin as well.
