| Identity and vehicle documents | Check the chassis or frame number, identification plates, and the numbers recorded on the ownership documents. | Compare the car with the original or current documents and ask the relevant vehicle authority how records for older vehicles are handled. | Identifiers are legible and consistent with the documents; any historical numbering differences are supported by official records. | Altered, missing, or unreadable identifiers; unexplained mismatches; or incomplete ownership paperwork. |
| Ownership and title history | Review the seller’s right to sell, registration history, and any recorded title restrictions or liens. | Use the official vehicle-record service or registry for the jurisdiction, where available, and confirm the seller’s identity and authority. | The seller and documents agree, and official records do not show unresolved restrictions. | Pressure to pay before documents are checked, unclear ownership, or an unresolved lien or title issue. |
| Service and accident history | Look for dated service invoices, inspection records, restoration photographs, and evidence of major repairs or accident damage. | Arrange records in date order and compare mileage, registration details, and descriptions of work across documents. | Records form a plausible timeline and support the seller’s description of the car. | Conflicting dates or mileage, undocumented major repairs, or gaps the seller cannot explain. Missing records alone do not prove a problem. |
| Frame, structure, and corrosion | Inspect the frame or chassis, floor, sills, body supports, suspension mounts, and other load-bearing areas for corrosion or damage. | View the underside in good light, ideally on a lift, and have a qualified mechanic assess suspect areas. | No visible structural perforation or poorly repaired damage; repairs, if present, are documented and professionally assessed. | Soft or perforated metal, fresh coating that hides the surface, distorted structure, or questionable welds near load-bearing points. |
| Engine and cooling system | Check for leaks, unusual noises, fluid condition, overheating, and persistent exhaust smoke. Ask to see a cold start. | Start the engine when cold, observe it at idle and operating temperature, and request a mechanic’s assessment if symptoms appear. | Starts and runs consistently, reaches a stable operating temperature, and shows no significant unexplained leaks or persistent smoke. | Overheating, knocking, heavy persistent smoke, contaminated fluids, or a seller who will not allow a cold start. |
| Transmission, steering, brakes, and suspension | Check gear engagement, clutch operation, steering play, brake response, and suspension noises or movement. | Have a qualified mechanic inspect these systems; road-test only when the car is roadworthy, insured, and legally permitted to be driven. | Controls operate consistently, with no severe pulling, excessive play, or unexplained mechanical noises. | Brake fluid leaks, ineffective braking, unstable steering, gears that jump out, or signs of unsafe repairs. |
| Electrical system, lights, and tires | Test the lights, indicators, instruments, charging system, and other fitted electrical equipment. Check tire condition, visible damage, and date markings where present. | Test each function and compare tire condition and tread with local road-safety requirements; ask a tire professional about age-related concerns. | Essential equipment works, wiring is secure, and tires have no visible cracking or damage and meet local requirements. | Exposed or improvised wiring, inoperative safety lights, damaged tires, or tires that fail local requirements. |
| Independent pre-purchase inspection | Assess the car’s overall safety, mechanical condition, repair needs, and consistency with its description. | Choose an independent professional familiar with older vehicles and request a written report before agreeing to buy. | The report identifies defects clearly and distinguishes urgent safety repairs from routine maintenance. | The seller refuses a reasonable inspection or discourages verification of the car’s identity and history. |
