For my insurance settlement of my stolen '98 ITR, I put together a list of ITR's that had been advertised for sale, then contacted the seller to determine just what they got (I found previous owners cooperative once I explained that it was for insurance settlement and nothing else). Once the adjusters realized that the ITR is rare, they were willing to negotiate an amount that I was happy with. In the end, my settlement (which includes the sales tax associated with whatever value you agree to) was about $1k less than I paid for the car just 9 months earlier back in 1999. Don't just go by what you think its value is, the insurance adjuster will need to see documentation of how you arrived at whatever value you feels is appropriate. Good luck.
