You have not specified your budget, but since you currently own a Maruti S-Cross, we assume you want nothing less than a mid-size SUV. Our default choice is the Hyundai Creta, which has been a tried-and-tested product for over a decade. It can be easily serviced across the country, giving you confidence for the many road trips you are planning.
Besides, the Hyundai Creta is a comfortable, spacious and feature-packed vehicle and is easy to spend long hours in. If you plan to do a lot of road trips, consider the 1.5 diesel variant. It is efficient and smooth when paired with a 6-speed auto.
You can also consider the Kia Seltos, which doesn’t have as good a sales network as Hyundai. But the Seltos, in its new avatar, is better than the Creta as a product. However, given your concern for a good service network, we would still advise you to go for the Creta.
