Compare the total cost of car ownership across buy-new, buy-used, lease, and keep-your-current-car — depreciation, insurance, maintenance ramp, and fuel over a real horizon, not just the monthly payment. Use when asked should I lease or buy a car, is it cheaper to keep my old car, what does this car really cost per month, or new vs used total cost. Produces the ranked scenario totals, per-month true cost, the assumption ledger, and the not-modeled list.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Car TCO Skill Cars are sold on monthly payments and owned on total cost — and the two rank options differently. Depreciation (the biggest cost of a new car) never appears on a statement; maintenance (the biggest fear about an old car) is usually smaller than a year of new-car depreciation. This skill compares buy-new, buy-used, lease-forever, and keep-current on the same total-cost basis over the same horizon. ## What This Skill Produces - **Ranked scenario totals** — every requested scenario over the same horizon, cheapest first - **True per-month cost** — total ÷ months, the number to compare against the payment the dealer quotes - **The assumption ledger** — depreciation curve, maintenance ramp, insurance deltas, all labeled - **The not-modeled list** — financing interest, jurisdiction taxes, reliability luck ## Required Inputs Ask for these if not provided: - **Which scenarios to compare** — any of: new price, used-equivalent price, lease terms, current car's value + annual maintenance - **Horizon** — years they realistically keep cars (default 8, labeled); short horizons flatter leasing, long ones flatter buying …

How to install
mdr add mohitagw15856/pm-claude-skills/car-tco@sha256:a410199b4dc917c3The line at the top of this page pins the label git:20260717.f2cb887, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
