I'm so sorry for your loss. My '73 is insured with Hagerty for $18K, 90,000 original miles. Her insurance co. will fight you hard for their money. They will try to undervalue it so be prepared to lawyer up. Get hold of your insurance co., too. You are going to be doing battle with her insurance co. FWIW, my son is a trial lawyer in Boulder. He owns a '77 Porsche SC and he would be worth a call. He loves to do battle with insurance companies. PM me and I'll give you his info. BTW, I've been thinking about selling my car. If you are interested let me know. Perhaps we can work something out.
Cheers, Mike
