ACV Vs Retail for insurance

Need help with a recent accident. I’ve read some other places on here that have helped but I need some advice for my situation. I have a 1997 Jeep Wrangler Sahara. The insurance adjuster sent me comparables to my vehicle to be anywhere from 6000 to 7500 for the Jeep similar to mine but not the same trim or specs. I wasn’t able to find many comps with a similar spec (V6 Sahara). The offer they gave me was $3800 with $225 in deductions ($3,600 total).

My jeep was in awesome condition. They went over ACV and retail, I just don’t see how I could come close to replacing my jeep with the 1/2 value they are offering.

Is this just how it is, or is there something I can do to make the offer higher to replace my jeep? Again, I’ve looked for comps and I have not seen any that aren’t absolute rust buckets.

Thanks for any advice!
