Quick-sale recovery

≈ $233

50% recovered

A dealer typically pays about 50% 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.
