Please include:

1. Budget and needs analysis
   - Check whether my budget is realistic.
   - Include a 10–15% reserve for first service, repairs, tires, fluids, filters, timing belt, brakes, or unexpected issues.
   - Estimate total cost of ownership, including fuel or charging, insurance, service, tires, repairs, taxes, and depreciation.
   - Warn me if the car is likely to be too expensive to maintain.

2. Best car type recommendation
   - Recommend suitable brands, models, engines, transmissions, and body types for my needs.
   - Explain typical strengths and weaknesses of the selected models.
   - Consider reliability, spare-parts availability, service costs, insurance, fuel consumption, and resale value.
   - Warn me about risky engines, transmissions, hybrid systems, expensive batteries, or hard-to-source parts.

3. Online history check before visiting the car
   - Tell me what to verify using the VIN code.
   - Check for mileage manipulation, accident history, stolen vehicle records, leasing or debt issues, technical inspection history, and ownership records.
   - Treat refusal to provide the VIN code before viewing as a serious warning sign.
   - Explain what documents or online reports I should request before traveling to see the car.

4. Physical inspection checklist
   - Create a detailed checklist for inspecting the exterior, interior, engine bay, tires, brakes, suspension, windows, lights, paint, body gaps, corrosion, and signs of accident repair.
   - Tell me how to check if the car was repainted or repaired after an accident.
   - Include checks for fluid leaks, cold start behavior, smoke from the exhaust, engine noise, warning lights, electronics, air conditioning, infotainment, windows, seats, sensors, and safety systems.
   - For electric or plug-in hybrid cars, include battery health, charging behavior, range, and battery certificate checks.

5. Test-drive checklist
   - Plan a 15–20 minute test drive including city roads, uneven roads, and higher-speed roads.
   - Explain what to observe during acceleration, braking, steering, shifting, suspension movement, engine temperature, noise, vibration, and straight-line stability.
   - For manual cars, check clutch bite point and gear shifting.
   - For automatic cars, check whether the gearbox shifts smoothly without jerks or hesitation.
   - For hybrid or electric cars, check smooth power delivery, regenerative braking, charging information, and battery behavior.

6. Price evaluation and negotiation strategy
   - Compare the listed price with similar cars on the market.
   - Identify whether the price is below market, fair, or overpriced.
   - Estimate the cost of visible defects and immediate repairs.
   - Prepare negotiation arguments based on real issues, not emotional pressure.
   - Suggest a fair offer, target price, and maximum price.
   - Give me scripts for responding to pressure tactics like “another buyer is coming today.”
   - Advise me not to pay a deposit unless the conditions are clearly written and refundable if hidden defects or legal issues are found.

7. Red flags and scam prevention
   - List warning signs that should make me walk away.
   - Include missing VIN, inconsistent mileage, unclear ownership, pressure to decide quickly, suspiciously low price, refusal of inspection, missing service records, fake payment requests, unpaid leasing, execution debt, or stolen-vehicle risk.
   - Explain when I should bring a mechanic or request an independent inspection.

8. Purchase contract and handover
   - Explain what must be included in the purchase contract.
   - Include buyer and seller details, vehicle identification, VIN, mileage, price, known defects, payment method, date and time of handover, number of keys, documents, and accessories.
   - Recommend adding all discovered defects to the contract.
   - Recommend using a handover protocol with odometer reading, document list, keys, service book, invoices, and current vehicle condition.

9. Safe payment and ownership transfer
   - Recommend safe payment methods.
   - Explain that ownership transfer should be completed within the legal deadline.
   - Mention that the buyer needs valid insurance before driving the car.
   - Include the documents usually needed for registration transfer, such as purchase contract, registration certificate, valid evidential inspection, proof of insurance, and identity document.
   - Recommend completing the transfer together with the seller or through the official online transport portal where available.

10. Final recommendation
   - Tell me whether I should buy the car, negotiate, inspect it further, or walk away.
   - Give me a risk rating: low / medium / high.
   - Explain the main reasons for your recommendation.
