Tony,
I hope your wife is well. That is by far what is most important!
As to the prompt service you have received, whether or not you are an Allstate insured, you cannot ask for much, if any, better. What you received is fairly standard standard most of the time for Allstate, State Farm, Progressive, and some of other good, large, insurers with presence these days (here in Central Florida). It is much better and less expensive to treat people well from the start. Disagreements and poor service get expensive real fast. Don't look a gift horse in the mouth!
The other property damage recommendations for you on MVA property damage repair are:
1) Use the body shop Allstate refers you to. Visit there at least once or twice ASAP while the car is being repaired. Establishing rapport with the people fixing your car goes a long way and prevents many problems and worries. If something isn't going right, don't start of getting angry. Talk it out!!!
2) If you have a newer model or valuable car, and you are not having the car fixed under your own Collision Coverage, which probably doesn't require it, do everything you can to get them to use original manufacturer parts.
3) If the crash was heavy and the car was newer or had value beyond mere transportation, pursue a claim for "diminution in value", which basically means: even thought the car was fully and properly prepared, it has still lost value as a result of the crash damage. I have never had an insurer voluntarily offer to pay a claim for this. You must ask!!!
Best regards,
Robert
