Given that your Maruti Ritz diesel is now 15 years old, it’s likely to depreciate further. We recommend selling it rather than applying for a fitness extension, as the resale value will only decline from here on, and diesel vehicle regulations may become more restrictive over time.
Regarding a replacement, considering your height (6'4"), the Hyundai Venue may feel too cramped, particularly in the rear seat and headroom department. A better fit for you would be either the Hyundai Creta or the Maruti Suzuki Grand Vitara, both of which offer significantly more space and comfort.
Between the two, the Hyundai Creta remains the most well-rounded midsize SUV, especially in its 1.5-litre petrol CVT variant. It’s smooth, refined, and perfectly suited for low running, assuming your future usage remains similar to the 2,200 km per year you've averaged with the Ritz.
