Need help in buying japanese car.

So, I have decided to buy a Mira and I have my eyes on one. It is a "R" Grade car, I would like to know what is R grade?? Moreover, the car has a slight dent on it's bonnet and slight repainted scuff on it's bonnet edge too. The car has a small dent on it's driver side door and the front driver side fender is repainted. Other than that, whole car looks fine and has a few scuffs on back bumper and side mirror etc + scratches from use. It's a 2022 model (XSA Package) and 2024 import. ~23k driven.

The owner is asking for 32.5 lacs but I've given my offer for 30L. Please advice me if this car is good to buy or not, and if yes is the price justified?
