Purpose

Brand residual value is one of the most consequential long-term metrics for an OEM — it shapes lease pricing, CPO program design, incentive strategy, and consumer perception of quality. Yet most brands only review residual rankings quarterly, long after depreciation trends have already damaged resale ecosystems and inflated lease costs.

Depreciation Tracker frames all analysis as brand value retention intelligence: how your brand holds value vs competitors over 3, 6, and 12-month windows, which models are depreciating fastest and need CPO or incentive support, where residual strength differs by state, and whether your new vehicles are still commanding MSRP premiums or sliding into discount territory.

How It Works

Execution flow. MCP tool calls are shown inline on each step.

↔ Parallel Execution

01a

Current Brand Avg Priceget_sold_summary

Calls get_sold_summary ranked by make, used vehicles, ranking_measure=average_sale_price for current period to get brand-level transaction prices.

01b

Prior Brand Avg Priceget_sold_summary

Same call for 6 months ago. Calculates retention % per brand and tiers: Tier 1 (>98%), Tier 2 (95–98%), Tier 3 (90–95%), Tier 4 (<90%).

Model Depreciation Curveget_sold_summary

For specific make/model queries, calls get_sold_summary at current, 60d, 90d, 6mo, and 1yr intervals to build a depreciation curve with monthly rate and annualized rate.

MSRP Parity Trackerget_sold_summary

Calls get_sold_summary with ranking_measure=price_over_msrp_percentage by make,model for new vehicles. Classifies each model as above MSRP, at MSRP, or discounting — tracks trend direction.

Geographic Value Varianceget_sold_summary

Calls get_sold_summary with summary_by=state for specific make/model to build state-level price index showing where brand holds value best and worst.

MCP Tool Calls

Limitations

US market only.
Depreciation curves require sufficient sold transaction volume per model per period — low-volume models (< 100 units/month) may have wide confidence intervals.
MSRP parity data (price_over_msrp_percentage) applies to new vehicles only; used vehicle depreciation is tracked separately.
Geographic variance analysis works best at state level — city or zip-level data may have insufficient sample sizes.
