AI prompt to research a new car before buying
AI prompt to research a new car before you buy: model shortlist, compare cost and safety, and dealer questions. Go and add your budget and driving needs.
Act as an independent car-buying advisor who helps shoppers research before they visit a dealer or sign paperwork.
Goal: Build a research brief that narrows my choice to a shortlist I can verify in person and online.
Context:
- Country or region (affects models, taxes, and incentives): [COUNTRY OR REGION]
- New, used, or open to both: [NEW / USED / EITHER]
- Total budget (purchase price, not monthly guess): [BUDGET RANGE AND CURRENCY]
- Monthly payment cap if financing (optional): [MAX MONTHLY PAYMENT OR LEAVE BLANK]
- Primary use: [COMMUTE, FAMILY, HIGHWAY, CITY, TOWING, OR MIX]
- Annual driving: [MILES OR KM PER YEAR]
- Must-haves: [SEATS, BOOT SPACE, EV/HYBRID/PETROL/DIESEL, AWD, SAFETY FEATURES, BRAND PREFERENCES]
- Nice-to-haves I can drop: [OPTIONAL FEATURES]
- Models I am already considering (optional): [MODELS OR LEAVE BLANK]
- How long I plan to keep the car: [YEARS]
- Parking and charging (if relevant): [GARAGE, STREET, HOME CHARGER YES/NO]
Success criteria:
- Every recommendation ties back to my must-haves and budget
- Compares at least three realistic options, not only flagship trims
- Separates facts I should verify (price, recall, trim availability) from your reasoning
- Includes total cost of ownership, not just sticker price
- Gives me dealer-ready questions and a short test-drive checklist
Instructions:
1. List up to 5 clarifying questions if my inputs are too thin. If you can proceed, say "Proceeding with assumptions" and list them.
2. State my non-negotiables in one short bullet list pulled from my inputs.
3. Propose a shortlist of 3 to 5 vehicles (make, model, and typical trim level). For each, say why it fits and one reason it might not.
4. Build a comparison table. Include model, typical price band, running costs, practicality, safety highlight, and warranty note as columns.
5. Sketch 5-year ownership costs: fuel or charging, insurance band (low/mid/high), maintenance tendency, depreciation risk in plain language.
6. List known issues, recalls, or model-year gotchas I must verify on official sources. Label each as "verify before buying."
7. Write 8 to 10 questions to ask the dealer (OTD price, fees, delivery date, demo vs new, financing APR, trade-in, cancellation policy).
8. Add a test-drive checklist of 6 items (visibility, braking, noise, tech, rear seat, charging or fuel flap if EV).
9. End with a "Next 7 days" plan: 4 concrete research steps before I put money down.
Output format:
Return sections 1 through 9 in order. Use the numbered headings exactly as above.
How to use
- Fill [MUST-HAVES] with deal-breakers only. Move preferences to [NICE-TO-HAVES] so the shortlist stays wide enough.
- Run once for a shortlist, then start a new message with "Deep dive on [MODEL]" for trim and option advice.
- Paste a dealer quote or listing link in a follow-up and ask "Does this OTD price look fair for [REGION]?"
Tips
- Monthly payment math hides total cost. Decide [BUDGET RANGE] on full price first, then check financing.
- Model-year changes matter. Ask for the specific year and facelift when comparing reviews.
- Treat incentive and tax claims as "verify before buying" even with web search enabled.
