Overpriced???

It's my dad's car, he bought in 2011 for 4.40 lakhs I believe, and it was the time when the 3 cylinder version was introduced. I seldom drive it as I'm an NRI. It takes ages for the car to reach a fair speed but otherwise its a very good car. Dad is planning to get a new one but is the car really worth 6.40 lakhs for the same model? There are other far better options if you are ready to shed another 100k.
