A dealer typically pays about 25% of market for a fast, guaranteed sale — the rest is the liquidity gap. An auction or private sale can recover more but takes time and fees. It’s why your Slabline Score weighs liquidity — and why insuring at market matters: a fire-sale recovers far less than the number you’re covered for.
Estimated from dealer buy-vs-sell spreads; actual offers vary by condition and demand.
