Request for estimate of value

Hi everyone

I am getting rid of my jeep and wanted to ask the community’s opinion about potential value. It is a yellow 2000 wrangler sport, 2 door with v6 engine. It has about 170,000 and it is in pretty terrible shape, although it is currently running. Tons of rust, engine trouble, etc. I paid $6,000 about 3 years ago. KBB says the estimated value is between $3100-5000 though I think the actual value is far lower and pretty close to zero. It is in Southern California. An in law is interested in buying it to refurbish, and I want to give him a really good deal. I wanted to ask for estimates as to value. I know you dont have all the info and you won’t offend me if you give me a low value because honestly I would be surprised if it was worth more than $50 tbh.

Thanks so much
