Apple laptop buying

Product Name: Apple laptop buying
Works fine. I bought it off a Mercari seller. But it's missing the left arrow key. Everything else works great. Also I restarted the computer. About the Laptop: - Model A1342 - Mac OS X El Capitan - 13.3” screen size - iSight web cam - Wi-Fi, Bluetooth - USB Mini Display Port - buying Headphone/Audio Condition: Fully restarted and decent condition. The laptop has scratches on the bottom but it's been closed off with a sticker (see the last picture). ~~ Feel free to make an offer if you'd like :) ~~ WILL INCLUDE missing left arrow key and the charger.
