INGREDIENTS
PROMPT
Create a skill called "Car Buying & Auto Loan Guardrails". Purpose: help the user evaluate car affordability and avoid common auto-loan traps (payment-only thinking, long terms, negative equity rollovers, pricey add-ons). When run: 1) Ask for [currency], net monthly income, essential expenses, and the proposed deal terms: vehicle price, down payment, trade-in equity, loan APR, loan term, and estimated insurance. 2) Estimate monthly all-in cost (loan + insurance + fuel + maintenance). 3) Flag risks and provide: - affordability range - recommended max term and target down payment - a checklist of questions to ask before signing 4) If negative equity exists, outline options (keep car, pay down, refinance, avoid roll-in). Safety: - Not financial advice. - No dishonest tactics. - Encourage user to read contracts and confirm final numbers.
How It Works
Car buying is a common financial trap: people focus on the monthly payment,
accept long loan terms, roll negative equity into the next car, and
underestimate insurance and maintenance. This skill calculates what you can
actually afford and flags the risks before you sign.
What You Get
- An affordability range (purchase price + total monthly cost including insurance, fuel, and maintenance)
- A financing checklist: APR, term length, add-on warnings, prepayment terms, GAP insurance
- Risk flags for long terms, high debt-to-income, and negative equity roll-ins
- A negative-equity decision guide (keep, pay down, refinance, or trade with caution)
- A dealer negotiation question list and a "walk-away" threshold
Setup Steps
- Know your monthly net income and essential expenses
- Get the vehicle price, your down payment, and any trade-in value
- Get the loan terms: APR, term in months, and any add-ons offered
- Estimate insurance, fuel, and maintenance costs
- Run the skill to see your all-in monthly cost and risk flags
Tips
- Total monthly cost (loan + insurance + fuel + maintenance) is what matters, not just the loan payment
- Loans longer than 60 months significantly increase the risk of going underwater
- Get pre-approved before visiting the dealer — it gives you negotiating leverage
- If you're upside down on your current car, the skill has a specific section for that
