The price asking for is Rs. 6.75 L
Thats too much. The 1.6 polo was around 7.2 lac (approx) here in Noida last year. Only 50k doesn't seem to be fine. I am not really sure about the price you should ask, may be you should start with 5.8 lac and bring him to 6 lac.
Give him few of following fundas:
- Its a petrol
- Polo 1.6 has been discontinued so you will have problem in repair and maintenance
- Fuel efficiency is also low
So, he may bring the price down. Try Carwale site, there you can evaluate you vehicles current worth.
Best of luck.
