Help Me Estimate a Fair Price for a Used 2009 Swift Dzire VXI

I am planning to buy my first car, a second-hand one, from my neighbor. I know him personally and am aware of the car’s history—it is a well-maintained, single-owner vehicle with a good service record. Car Details: Make & Model: Maruti Suzuki Swift Dzire VXI (Petrol) Year: 2009 Kilometers Driven: 1,00,500 km Condition: Well-maintained, single-hand driven, with minor scratches on the back (nothing major) Reason for Sale: He cannot use it in Delhi due to registration restrictions and owns other new cars. Registration: Dehradun (Uttarakhand), but I will have to transfer it to my location in West Uttar Pradesh. I plan to use the car for a year or two before upgrading to a new one. Given these factors, what would be a fair price for this car? I want to ensure I get the best deal while also considering RTO transfer costs. Any insights would be greatly appreciated! Thanks in advance!
