Vehicle Safety Checks When Buying


Buying a Used Vehicle.

When looking to buy a used vehicle, there are several important factors to consider to ensure you are making a safe and informed decision. From checking the vehicle's history to inspecting its condition, taking the time to ask the right questions and carry out thorough checks can help you avoid potential pitfalls down the road. In this article, we will provide you with a comprehensive list of tips and guidelines to follow when buying a used car privately.

Even though the vehicle is under 12 months old or falls within the 3-year period exempt from needing an MOT, it remains crucial to ensure the vehicle is safe and operating effectively. The safety of all occupants and other road users is very important.
Taking the time to inspect the vehicle thoroughly can prevent potential issues and keep you, your passengers and others safe on the road.

When it comes to buying a vehicle, especially a used one, seeing the vehicle in person is crucial. Pictures can be deceiving, and what looks great in photos may not be as impressive when you see it up close. By taking the time to inspect the vehicle in person, you can get a better sense of its overall condition, any potential issues, and whether or not it's the right fit for you.

If you come across a vehicle listing on BNBids with a vague or unclear description, don't hesitate to reach out to the seller for more information. Ask specific questions about the condition of the vehicle, any known issues, and whether any warranties or guarantees are included. Clarifying these details upfront can help ensure a smooth and successful transaction.

It can be tempting to purchase the vehicle without seeing it in person. However, when it comes to buying vehicles, we highly recommend that buyers see the vehicle in person before making any final payments. This simple step can help you avoid potential scams, hidden issues, and costly mistakes down the road.


Seeking a Second Opinion:
If you don't feel confident about carrying out the necessary checks on your own, it's always a good idea to seek a second opinion from a trusted mechanic or professional. A qualified expert can thoroughly inspect the car and identify any underlying issues that may not be immediately apparent. Having a second opinion can provide you with added peace of mind and assurance in your decision-making process.

Why is Seeing the Vehicle in Person Important?
When you see the vehicle in person, you can check for any signs of damage, wear and tear, or mechanical issues that may not be apparent in photos. You can also get a feel for how the vehicle drives, handles, and sounds, which can give you valuable insight into its overall condition. Additionally, seeing the vehicle in person allows you to ask the seller any questions you may have and negotiate a better deal if needed.



Benefits of Seeing the Vehicle in Person allows you to check the following:

Vehicle Documents.
  • Can the seller show you the V5C registration document? You won't be able to tax the car without it.
  • Is the seller the registered keeper on the V5C? If not, why sell for someone else.
  • Does the registration document have a watermark.
  • Check for spelling mistakes on the registration document.
  • Do the VIN, engine number and colour match the details on the V5C.
  • Is the VIN plate original or been tampered with.
  • Do VIN numbers etched on glass or lights match the VIN plate and V5C.
There is a number of Reasons for Needing vehicle Glass Replacement, such as: Attempted Theft or vandalism, Stone Chips, Animal Damage.
There is no real reason to scratch the glass to remove etched-in marks just because of a glass replacement.

For vehicles in countries out-side the united kingdom - buyer (or seller) can check with their vehicle registration authorities.


Vehicle Mileage.
  • Overall Mileage: The overall mileage of a vehicle is a good indicator of how much wear and tear the car has experienced. High mileage may indicate that the vehicle has been used extensively, while low mileage could suggest that the car has been lightly used.
  • Inspect the Odometer: Make sure to inspect the odometer for any signs of tampering or fraud. An altered odometer reading can greatly affect the value of a car, so it’s important to verify the mileage is accurate.
  • Check for Inconsistencies: Look for any inconsistencies in the mileage readings, such as mismatched service records or odometer readings that don’t add up. These discrepancies may indicate that the vehicle has been tampered with.
  • Check mileage from the last MOT service, this will give you a better idea of the vehicles mileage.


Vehicle Accident damage. (if any at all)

Exterior Inspection:
  • Check for Misaligned Body Panels: Misaligned body panels, such as uneven gaps or crooked lines, could indicate that the vehicle has been repaired poorly after a collision.
  • Look for Paint Overspray: Paint overspray on moldings, weatherstripping, or chrome trims could suggest that the car has been repainted, potentially to hide previous damage.
  • Inspect for Rust or Corrosion: Rust or corrosion on the body of the vehicle could be a sign of hidden damage caused by an accident.
Structural Inspection:
  • Check for Weld Marks: Weld marks on the frame or undercarriage may indicate that the vehicle has undergone structural repairs due to a collision.
  • Inspect Suspension Components: Look for signs of bent or damaged suspension components, such as control arms or struts, which could affect the handling and safety of the car.
  • Examine the Frame: Use a frame measuring tool to check for any bends or twists in the vehicle's frame, as these could indicate significant accident damage.
Mechanical Inspection:
  • Inspect the Engine Bay: Look for signs of leaking fluids, loose wires, or damaged hoses and radiators which could indicate underlying mechanical issues caused by a collision.
  • Check the Steering and Braking Systems: Test the steering for any vibrations or pulling, and ensure the brakes operate smoothly without any strange noises or sensations.
  • Test Drive the Vehicle: Take the car for a test drive to check for any unusual noises, vibrations, or handling issues that could point to accident-related damages.
Vehicle Safety.
  • Are the tyres in good condition? Tyres with less than 3mm of tread will have to be replaced soon.
  • Is the spare wheel or tyre inflator kit in serviceable condition and in the vehicle.
  • Check child safety locks works properly.
  • Is the jack and its attachments in the vehicle and in working order.
  • Do all the seatbelts operate correctly - if the seat belt is frayed or damaged at all - any damage to seat belts is an MOT failure - it must be replaced.
  • If airbags are fitted, Check that warning lights operate as described in the handbook – normally they will come on with the ignition and then go out
  • Do all lights and windscreen wipers/washers work correctly.

  • Does the oil warning light go out as soon as the engine starts.
  • Check for knocking noise when revving the car engine. There are several possible causes for engine knocking.
  • Any signs of excessive visible exhaust emissions.
  • Does the clutch operate normally? A noise when you press the pedal or a high biting point could mean that repairs will be required soon.
  • Is the catalytic converter in good condition? Look for a recent emissions test, either alone or as part of an MOT. This will confirm that emissions are within the stringent limits applied to modern cars.
  • Is there sludge on the underside of the oil filler cap? This could indicate poor servicing or predominantly short journey use.
  • Is the oil level right showing on the dip-stick. a well maintained engine should have the correct level of oil unless there is a issue.
  • Has the cam belt / chain been replaced according to the service schedule.
  • Blue/Dark exhaust smoke from a running car engine - this is usually a clear sign that the car engine is burning oil, this can be related to:

  3.  - Malfunctioning PCV Valve.
  4.  - Worn Engine Oil Seals.
  5.  - Inlet Manifold Leaks.

Vehicle Windows, Locks and Controls.
  • Do all the locks, including central locking and remote control, work properly?
  • Do all windows, including any sunroof, open/close normally?
  • Any signs of forced entry, damaged or different locks, suggesting they've been replaced?
  • Have you got all the right keys - Check the handbook to see which keys were provided when the car was new. Modern keys are expensive to replace, particularly the coloured 'master' key provided by some manufacturers to programme new spare keys.
  • Are locking wheel nuts fitted - Check that the special adapter is in the vehicle and that it fits the fitted locking nuts on the vehicle.
  • Check the vehicles controls such as the heating, ventilation, air-conditioning, sound-system, navigation, electric seats etc.
