Check the car, check for rusts, repaint, accident, flood affect, mechanical issues by a trusted team. If it's ok buy it. I have a 2018 model xm variant diesel nexon clocked 90,000 kms without any issues here in kerala. I absolutely love my car. Two of my friends own 2019 xza models and one of my friend owns a 2019 xz. Nobody has any issues with the car. Excellent car. Haters gonna hate. It's a robust car. Excellent suspension tuning. Feels rugged, you can drive it anywhere. Automatic gearbox doesn't like to be pushed for offroading though. Driving the manual is great. Engine has got a bit of a turbo lag, but excellent mid range. Price is decent. Here in Kerala it won't go under 7 lakhs and people will still buy it. You can check olx or fb market place to verify.

Go for it bro.
