This thread has turned ugly, and it's up to Iggy as to what to do in the end. It sounds to me like he has a good character, and if he does have to get a lawyer, he will act in good faith and not go for what he doesn't feel he's due. The catch-22 about that is, the lawyers will all want to over-demand by about 1000%, as it's not worth the going rate for a lawyer to fool around with a damage claim of a few thousand dollars, or even $20,000.
If I were in his shoes, I'd sit down and write a letter to both insurance agents, with a copy (cc) to the State of (_______) insurance commissioner or whatever that state uses to enforce fair practices in insurance, and send the letters to the two agents via certified mail with return receipt. That letter should contain EVERYTHING, so as they can't say later that they didn't know what accident you're talking about, etc. It should have (date, time, and repeating all of the details of the accident), the police report, photos of damage, and copies of any receipts to date, and any estimates for repairs to the cars, along with what if any other costs you have, or will have to, cover. Add all that up, and figure in a little for time & effort you lost, and write that you demand that this be settled by (___) date, or you will refer the matter to an attorney.
Iggy, if you do that, and still nothing happens by the date you demanded, which could be whatever you want that sounds fair; maybe 10 days, you can go get a lawyer without a guilty conscience later, as long as you don't let the lawyer talk you into creating all kinds of fake injuries from impotence to sore toenails, and an unfair sum for pain & suffering. Also be sure to get this going before the statute of limitations expires, which in many states is 1 year from the date of the accident.
