Genuine price of used Xbox S

What should be the genuine buying price of Xbox series S which is 2.5 years old, no scratches and in prefect condition both internally and externally. Provided that controller also has no marks or scratches, sensitivity is also good.

I’m confused because some are saying it should be 15-16k as it waa released/launched in 2020 as new imported version is available for 30k.

While some also say 20-21k is good price as it will last for many years to come because next gen will launch in 2028
