Welcome aboard Vicky, wishing you a pleasant stay here.
Three days back I was also at Patnitop itself after visiting Vaishno Devi. A wonderful place it is I must say.
Coming to your query:
If the Punto can be had for a mouth watering price then go for it, take the advantage of poor resale value of Punto. BTW
Punto is really good for bad roads as well as the wide corners on the roads there, fun filled moments you know.
Get the vehicle thoroughly checked at the A.S.S. and go for it if everything found well.
All the best for your purchase.
