| Primary Use | Choose the vehicle’s main purpose before browsing listings. | Daily commuting, family transport, long-distance travel, delivery work, or occasional use. | A clear use case prevents buying a vehicle that is too large, inefficient, expensive, or unsuitable for regular driving conditions. |
| Passenger Capacity | Specify the usual and maximum number of occupants. | 1–2 occupants: compact car; 3–5 occupants: sedan or hatchback; 6–8 occupants: van or three-row vehicle. | Interior seating and child-seat compatibility are difficult to judge accurately from photos alone. |
| Cargo Requirement | Measure the items that must fit regularly. | Small luggage: hatchback trunk; bulky equipment: wagon or van; heavy loads: vehicle with a suitable payload rating. | Advertised cargo volume may not reflect the usable shape, loading height, or rear-seat configuration. |
| Driving Environment | Match the vehicle to roads, weather, and traffic conditions. | Urban traffic, highways, rural roads, steep terrain, snow, heavy rain, or unpaved roads. | Ground clearance, drivetrain, braking performance, visibility, and fuel economy vary by operating environment. |
| Purchase Budget | Set a maximum amount for the vehicle itself. | Use the local currency and compare the same tax-inclusive or tax-exclusive price basis. | Online prices may exclude taxes, registration, inspection, delivery, auction fees, or import charges. |
| Total Ownership Reserve | Keep money aside for costs after the purchase. | Reserve approximately 10%–20% of the vehicle price for initial maintenance, documents, transport, and unexpected repairs. | A low listing price can become expensive after registration, shipping, repairs, and compliance work. |
| Financing Limit | Define the maximum affordable monthly payment and total repayment. | Compare deposit, interest rate, loan term, fees, currency risk, and early repayment conditions. | A lower monthly payment can result in a higher total cost over a longer term. |
| Vehicle Age | Set a preferred age range and an absolute maximum age. | Record the first registration date, not only the model year. | Older vehicles may have more wear, fewer safety features, and higher maintenance requirements. |
| Mileage | Use mileage as one condition indicator rather than the only buying rule. | Check whether mileage is consistent with service records, inspection reports, and vehicle age. | A well-maintained higher-mileage vehicle may be safer than a poorly maintained low-mileage vehicle. |
| Service History | Require evidence of regular maintenance. | Look for dated invoices, maintenance entries, inspection records, and records of major repairs. | Documented history helps verify mileage and identify upcoming maintenance needs. |
| Accident and Ownership History | Confirm legal ownership and previous damage. | Request the vehicle identification number, title status, number of owners, accident details, and salvage or flood information where available. | Photos may hide structural repairs, corrosion, flood damage, or unresolved ownership issues. |
| Mechanical Inspection | Make an independent inspection a purchase condition. | Inspect the engine, transmission, brakes, suspension, tires, fluids, underbody, electronics, and diagnostic system. | An independent inspection reduces the risk of relying solely on seller descriptions or edited images. |
| Safety Equipment | List essential safety features for the intended use. | Check airbags, anti-lock braking, electronic stability control, child-seat mounting points, tires, and available crash-test information. | Safety equipment and legal requirements can differ by production year and destination country. |
| Fuel or Energy Type | Choose an energy source supported by local infrastructure. | Petrol, diesel, hybrid, or battery-electric; verify fuel availability, charging access, battery condition, and local restrictions. | Operating costs and usability depend on fuel prices, charging access, climate, and service availability. |
| Import and Compliance | Confirm that the vehicle can legally enter and operate in the destination country. | Check emissions rules, steering side, lighting standards, conformity documents, import age limits, customs duty, and registration requirements. | A vehicle that is legal in the selling country may require costly modifications or may not be registrable elsewhere. |
| Delivery and Payment Security | Define how the vehicle and funds will be exchanged safely. | Use a written purchase agreement, verified payment details, secure logistics, tracking documents, and clear refund conditions. | International transactions add distance, currency, fraud, shipping, and dispute-resolution risks. |
| Final Decision Rule | Define non-negotiable requirements before contacting sellers. | Separate criteria into essential, preferred, and unacceptable conditions; reject listings with missing documents or unverifiable claims. | A written checklist makes it easier to compare listings objectively and avoid impulse purchases. |
