Kayra Cabs offers one of the more affordable self-drive car rental options in Delhi NCR. You can hire a Maruti Brezza (petrol, manual, 5-seater) from them for around ₹2,500/day, with a minimum booking of 2 days. Vehicles are well-maintained, and there are no surprise hidden fees—fuel is extra, and you need a valid driving licence. If you stay longer or choose less expensive models (hatchbacks vs SUVs), average cost per day drops further. If you like, I can compare Kayra’s rate vs others for the same model to see which is cheapest.
