The nexa showrooms are excellent, but the made many mistakes as I have extended my warranty and the give me a document but after few days I came to know that it was a false paper.
The Car is outstanding, driving posture is also excellent, I didn't feel any kind of pain in my body after reaching Thimphu, Bhutan from Bankura, W.B., India in approx 24 hrs of continuous journey with my family. It's a great car. Go for it!
But keep in mind while buying car that the sales man can fraud you by giving false documents of nexa card and extended warranty.
Then when the period of extended warranty start they will tell you that 'No you don't have extended warranty'.
