What it does
The Car Dealership is an agent skill from mohitagw15856/pm-claude-skills. Simulate the car-buying gauntlet before you walk in — the four-square worksheet, the payment-question trap, the trade-in shuffle, and the finance office's second sales floor, all run against your actual deal. Use when asked practice negotiating at a dealership, simulate the finance office, what tricks will the dealer use, or prep me before I buy a car.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Education, covering Educational content. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Asked practice negotiating at a dealership
- Simulate the finance office
- What tricks will the dealer use
- Prep me before I buy a car

- “/the-car-dealership”
What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
The Car Dealership loads about 1.4k tokens when it runs. Until then it costs about 138 tokens; SKILL.md has 748 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Simulate the car-buying gauntlet before you walk in — the four-square worksheet, the payment-question trap, the trade-in shuffle, and the finance office's second sales floor, all run against your actual deal. Use when asked practice negotiating at a dealership, simulate the finance office, what tricks will the dealer use, or prep me before I buy a car. Produces the showroom and finance-office transcripts with the salesperson's playbook notes, the deal outcome vs your targets, and a debrief with the holds that would have worked.
The Car Dealership Skill
The dealership is two negotiations wearing one showroom: the car price out front, and the finance office in back — where the real margin often lives, sold to a buyer whose guard dropped the moment they heard "congratulations." This skill runs both rooms against your actual numbers: the four-square worksheet that blends price/trade/payment into fog, the "what payment works for you?" trap, the trade-in shuffle, and then the F&I gauntlet of add-ons and rate markup. Every move gets named in the dealer's private notes, and the debrief hands you the exact holds.
What This Skill Produces
- The showroom transcript — 8–14 exchanges with the salesperson's playbook note after each move
- The finance-office transcript — the second negotiation most buyers don't know they're in
- The outcome — the deal reached vs. your targets, and what the dealer's notes say they'd have accepted
- The debrief — every soften-point with the hold that was available, plus the one-page crib sheet to bring
Required Inputs
Ask for these if not provided:
- The deal shape — the car (new/used), your researched target price (have one — the simulation exposes what happens without it), cash/finance/lease intent
- The trade-in, if any — and its independently-checked value (no number = finding #1; the shuffle feeds on unpriced trades)
- Financing reality — pre-approval rate in hand? (walking in without one hands the rate conversation to the F&I office)
- Your tells — in love with the specific car? Need it this week? The simulation uses whatever leverage you hand it, realistically
Framework: The Two Rooms
Room one — the showroom moves: the payment question ("what monthly works for you?" — answering it surrenders the price; the counter is "let's settle the out-the-door price first") · the four-square (price, trade, down, payment on one sheet — fog by design; the counter is one number at a time, out-the-door) · the trade-in shuffle (great car price, terrible trade number, or vice versa — the counter is negotiating them as separate transactions) · the manager walk ("let me talk to my manager" — theater and a pacing device) · the today-only urgency (the deal that dies at midnight rarely does).
Room two — the finance office: the rate markup (the quoted APR may carry dealer reserve — the counter is your pre-approval on the desk: "beat this or use it") · the add-on cascade (VIN etching, paint protection, nitrogen, extended warranty, GAP — each priced at 3–10× cost; some, like GAP on a long loan, are legitimately worth pricing elsewhere) · the payment-packing move (add-ons quoted as "just $9 more a month" — ×72 months, out loud, every time) · the menu close (three columns of bundles, none labeled "none of these" — that column exists; ask for it).
Mechanics to honor: out-the-door price is the only number that can't be shuffled · everything is negotiable until signed, nothing after · the walk-out is a legitimate and often winning move, and one run should show it working · four hours in the building is a tactic, not bad luck.

Output Format
Dealership Run: [car, targets]
Simulation — a plausible adversarial reading, not a prediction.
Room One — The Showroom
[Transcript. Dealer's note: after each move, naming the play and reading you: "asked their payment — they answered. Working payment now, price is loose."]
Room Two — The Finance Office
[Transcript: rate, add-ons, menu — with the ×72 math shown wherever "per month" appears]
The Outcome
[Deal vs. targets · the dealer's notes on where you left money · the walk-out branch: what re-engagement looked like]
Debrief — out of character
| Moment you softened | The move | The hold (exact words) |
|---|---|---|
| [Plus: the crib sheet — out-the-door only · trade separate · pre-approval on the desk · ×months every add-on · the none-column ask] |
Quality Checks
- Every dealer move comes from the named playbook, visible in their notes
- The payment-question trap appears and its consequence is shown
- The finance office gets its own act — not an epilogue
- Add-ons are priced ×term aloud, and any genuinely-worth-considering one is flagged honestly (price it elsewhere)
- The debrief's holds are verbatim words, not advice-shaped vibes
Anti-Patterns
- Do not cartoon the salesperson — it's a professional running a standard playbook; naming the plays is the training
- Do not let the simulation reward answering the payment question — that's the fail state it exists to train out
- Do not treat all add-ons as scams — mark the price-it-elsewhere ones honestly; credibility is what makes the rest land
- Do not skip the walk-out branch — buyers who've rehearsed leaving negotiate differently
- Do not stay in character in the debrief
Example Trigger Phrases
- "Practice negotiating at a dealership."
- "Simulate the finance office."
- "What tricks will the dealer use?"
- "Prep me before I buy a car."
