Here's my take.
1. Suck it up and get your car repaired under an insurance claim.
2. Start legal processes to recover your loss in time, insurance deductible and rate increases in your insurance. Never give up on this ... make his (and his families) life miserable with continual trips to court. Make them pay out their a$$ in attorney's fee's. Don't let him get away with this.
3. Think of other things you can do to make his life miserable. I would put the fear of God into this guy until he conceeds and convinces his family to write you a check to get you off his back. Think about it, you can do many things that are perfectly legal that will make his life miserable ... and many more that border on illegal. Just be careful.
Good luck to you ... but most of all, get your ride fixed!
