I wasn't sure where to post this so let me know if you need to move this topic.
Can I devalue parts that I bought 15+ years ago?
Example: I paid $250 for a set of VW heads back in late 2000. Now I want to use those heads in my build. Now they are more accurately only worth $100 or $150.
Can I claim fair market value on them even though I did pay $250?
Not trying to cheat, just curious what everyone thinks.
