The Maruti Suzuki Victoris would be a natural upgrade from your Wagon R, especially since in remote areas, where Maruti’s widespread service is a significant advantage. The Victoris is reliable, well-built, and offers a smooth drive, which should satisfy your father. The only possible deal breaker is the rear seat space, which is less spacious by mid-size SUV standards, especially in terms of headroom. This could be a problem for tall family members, especially if everyone is travelling together.
Please take a test drive and make a point of checking the cabin space before making the purchase. A slightly more spacious alternative is the Hyundai Creta, which is also a tried-and-tested model. The Hyundai Venue is too cramped, and the Mahindra options are larger but not as user-friendly.
