Insurance lowballed my totaled car — fighting back with my own comps, any hope?

Yes, absolutely push back. I went through almost the exact same thing two years ago. Their first offer was a joke, I sent over my own comps the same way you did, and they came up meaningfully on the second offer. Didn't get everything I wanted but it was way better than just accepting the first number. The key for me was being really specific — like, here's listing A, here's listing B, here's why they match MY car and yours don't. Keep your receipts for anything you put into the car recently too.

Those "criteria" they quote you about distance and mileage tolerance? They apply them loosely when it hurts you and strictly when it helps them. Classic. Don't let them lecture you about their methodology when they're the ones who violated it first. You're doing exactly the right thing by calling that out in writing.

Honestly, the first offer on a total loss is almost never the final one — and adjusters know that. The valuation tools they use have real flaws and the comparable selection can be manipulated, sometimes intentionally, sometimes just sloppily. When a claimant comes back organized and specific like you're doing, it gets taken more seriously internally. I'd also ask them in writing to explain exactly why each of YOUR comps doesn't qualify. Make them do the work to justify their number, not just assert it.

A few things worth knowing: most states require insurers to pay actual cash value, and if you can show their comps don't reflect that, you have legitimate grounds to dispute. Also, if you feel like they're stonewalling you after a good-faith negotiation, you can file a complaint with your state's department of insurance. That sometimes gets things moving faster than any number of emails. Not telling you what to do legally, just stuff I've seen matter in these situations.

Don't lowball yourself when you counter. If your research shows the car is worth X, say X — not X minus a buffer to seem reasonable. They're not going to meet you halfway out of goodwill, they're going to try to land somewhere below your counter no matter what. Give yourself room to negotiate.

Not legal advice, but total loss disputes are one of the more winnable fights with insurers because the methodology is actually documentable. If they used non-comparable vehicles, that's a concrete argument, not just a feeling. If negotiations stall, a PI attorney or even a public appraiser can sometimes help you get an independent valuation that carries more weight. Many PI attorneys will at least give you a free consult on something like this.

How many comps did you send them, and how close was the mileage match? I ask because they'll pick apart anything they can. If even one of yours has a detail they can argue about, they'll focus on that and ignore the rest. Just want to make sure your list is airtight before you're too deep into this negotiation.
