Suggestions about new MacBook purchase

Looking at buying a 2022 MacBook Pro m2. Machine has some water damage so it’s selling for $480. I’m not super tech savvy but I have the required screw drivers and can follow a YouTube video. Any suggestions for what to look for/test if I meet up with the seller? Is this just a bad idea in general? I’m just hoping to get a new school computer that’ll last 3+ more years for a good price. I appreciate any help!
