>They gave me $50 for my goose neck ball and $600 for the brand new rims and tires that cost me $4000.

Generally you don’t get anything for mods. So that’s at least something. If you have the original rims you can ask to put those back on and keep your new ones, I was successful once doing that on a Mini Cooper.

>and they wanted $200 to give me something I can actually fight with.

$200 is totally worth it if it’s thousands extra you get. Appraisers don’t work for free
