Cohort Benchmarking
Benchmark a dealer group against a custom cohort — same geography, same brand mix, same size tier for apples-to-apples comparison
Purpose
Ranking AN against LAD is misleading when their scale, geography, and brand mix differ significantly. A more rigorous analysis compares a dealer group to its true peer cohort — similar scale, overlapping markets, similar OEM exposure. Cohort Benchmarking builds a custom peer set and runs the full comparison.
Cohort Benchmarking lets analysts define the comparison cohort by geography, brand exposure, or size tier — then runs the same multi-dimensional analysis as Group Benchmarking against only those comparable peers. Output includes a cohort-normalized quintile score and gap-to-best-in-cohort metrics.
How It Works
Execution flow. MCP tool calls are shown inline on each step.
get_sold_summaryLoads profile or prompts user for cohort criteria: geography (states), brand/OEM exposure, or size tier (volume range). Identifies matching dealer groups in MarketCheck data.
get_sold_summaryCalls get_sold_summary filtered to cohort geography and brand parameters for current and prior periods. Extracts all cohort groups' volume, ASP, DOM.
Ranks all groups within the defined cohort across Volume, ASP, DOM, and Efficiency Score. Assigns cohort quintile scores.
For the focus group, identifies gap-to-best and gap-to-median on each metric. Quantifies opportunity (e.g., 'closing DOM gap to cohort leader would add X efficiency points').
MCP Tool Calls
| Tool | Calls | Purpose |
|---|---|---|
get_sold_summary | 3–5 | Cohort group volume/ASP/DOM current and prior, plus optional brand filter calls |
Example Output

Cost Estimate
10 analyses/month ≈ $1–3
Limitations
- US market only.
- Custom cohort quality depends on specificity of user criteria — overly narrow cohorts may have too few groups for meaningful quintile scoring.
- Geographic cohort filtering relies on state-level data; multi-state groups are not automatically filtered to only their overlapping markets.
