Please suggest the best car within a budget of Rs 20 lakh. My key requirements are fun-to-drive performance, ventilated seats, wireless charging, auto hold and hill assist, comfortable rear seats, a rear HD camera with dynamic guidelines, and a 360-degree camera.

Unfortunately, in your budget, no car ticks all those boxes without compromising in at least one area. The best option would be to increase your budget by a few lakhs and get the Hyundai Creta N Line N10, which offers all the features you are after, as well as a fun-to-drive package, including a potent 160hp turbo petrol engine and a well-set-up chassis. 

However, if you absolutely must stick to your budget of Rs 20 lakh, consider the Mahindra XUV 3XO AX7 Luxury 1.2 T-GDi. You get a potent 131hp turbo petrol engine, a robust chassis that offers good ride comfort and handling, a comfy and spacious rear seat and a good feature set. All you miss out on are ventilated front seats.
