As far as the other insurance offering you compensation for the depreciation in value, just make sure that it's part of the subrogation package -for damages to the car only- and not also fulfilling a pain and suffering claim that you have to sign off on.
Also, if you just had the accident, take your family to your physician, get a clean bill of health for them, and have this billed to your insurance (you'll get a claim number assigned to the accident). Soft tissue damage takes about 7 to 10 days sometimes, before you experience any pain. For any pain and suffering, loss of wages from work (this includes holiday time, comp time etc, not just sick time), diminished capacity, you are entitled to a dollar figure within reason as compensation. The insurance will not mention it.... you have to bring it up, and provide all the necessary documentation to substantiate your claim as part of a 'demand' package, which will then involve negotiating a settlement with the insurance company. There's a distinction to be made here... This is not arbitrarily trying to "milk" the insurance company, it a compensation for everything else you and your family had to deal with, in addition to the damage to your car. You decide a fair value for that....
In addition, do not sign a parent/guardian release for your son, unless the following 2 conditions are met:
-You are absolutely sure he has no injuries at this time, and there is no chance of a likelihood of pain resulting from this in the future (until he is 18, at least). You have to make this determination with the help of his doctor, and it's not an easy one.
-You are financially compensated for signing the above release form.
Sorry to be so long winded, but back to your original question, -and this is just what I would do, so my opinion and a buck could probably get you no more than a cup of coffee- since they will not total the car, I would get it repaired, do a private sale with full disclosure to a potential buyer and take the hit on the front end with resale value (trade in probably won't get you close to what you're looking for), using the other insurance's check to offset that (keeping in mind what I mentioned), and using whatever you can get for pain and suffering in addition, to purchase another clean, clear, preinspected vehicle that you can drive with peace of mind. If you do get something worthwhile for pain and suffering, you can either -like I said- use it to help with the newer car's purchase or -hint, hint- throw it into a 529 for your son.
