MacBook Air 13 inch for parts or repair

I purchased this in 2017 so not completely sure if this is a 2015 or later model. Have owned it for 4 years- purchased at apple store. I tried updating the laptop and it seemed to have malfunctioned. The screen and keyboard are completely working and can be fixed by apple support with cost. Selling for either repair or parts. Physically in good condition 256 GB
