Side-by-side comparison
| Dimension | CCC ONE | Mitchell WorkCenter |
|---|---|---|
| Used by (major carriers) | GEICO, Allstate, USAA, Nationwide, American Family | Progressive, Liberty Mutual, Auto-Owners, Erie |
| Approx. US market share | ~50% of total-loss settlements | ~30% of total-loss settlements |
| Typical comparable count | 4-8 comparables per report | 5-10 comparables per report |
| Typical search radius Mitchell's wider radius is a frequent attack surface — distant comparables aren't local replacement cost. | 50-100 miles (algorithmic) | 100+ miles (often too wide) |
| Adjustments shown | Mileage, condition, equipment, typical-negotiation | Base value, condition, equipment, mileage (separate columns) |
| Typical-negotiation discount This is one of the cleanest divergences — disputable on CCC, irrelevant on Mitchell. | Yes (conditional, ~7% on advertised prices) | No (Mitchell does not apply this category) |
| Condition rubric | Poor / Fair / Good / Very Good / Excellent | Poor / Fair / Good / Very Good / Excellent (different multipliers) |
| Report transparency | More transparent — math is visible per comparable in full report | Less transparent — adjuster summary often hides per-line math |
| Frequency of revisions on counter | Frequent — CCC re-runs are common when errors are documented | Less frequent — Mitchell pushback often requires supervisor escalation |
Bottom line
If you're disputing a CCC ONE valuation, your strongest leverage is the typical-negotiation discount and verifying the per-comparable math (CCC publishes its methodology, which makes errors easy to cite). If you're disputing Mitchell, your strongest leverage is the locality of comparables (Mitchell often pulls from 100+ miles) and the condition grade. Either way, request the full report — never settle from the summary.
