Since you want to upgrade from your Tata Nexon to a fun-to-drive manual car, you should consider the Volkswagen Taigun 1.5 TSI MT. The Taigun is one of the best handling midsize SUVs, and its 150hp, 1.5-litre turbo-petrol is one of the punchiest around.
You could also consider the Skoda Kushaq or the Skoda Slavia/Volkswagen Virtus, but none of those get a manual gearbox option with the 1.5 TSI engine - only a 7-speed dual-clutch automatic.
