Buying a Car With Advisories on the MOT — Which Matter

Understanding MOT Advisories

When purchasing a used car in the UK, the MOT (Ministry of Transport) test is a crucial aspect to consider. This annual test assesses a vehicle's roadworthiness, safety, and emissions. While a pass is essential, many vehicles may come with advisories — notes made by the tester indicating potential issues that may need attention soon. Understanding these advisories is vital for any buyer, as they can significantly impact the vehicle's condition and future costs.

Advisories are not failures; they are warnings that something may require attention in the near future. However, not all advisories carry the same weight. Some may be minor, while others could indicate serious underlying problems. As a prospective buyer, it’s essential to differentiate between the two to avoid costly mistakes.

Common MOT Advisories and Their Implications

1. Tyre Condition

Tyres are one of the most critical components of any vehicle, and their condition can greatly affect safety and performance. Common advisories related to tyres include uneven wear, low tread depth, or sidewall damage.

How to Spot It

To check for tyre issues, visually inspect each tyre for signs of wear. Use a tread depth gauge or the 20p test: insert a 20p coin into the tread; if the outer band is visible, the tread is too low. Look for bulges or cracks on the sidewalls, which could indicate structural damage.

What It Means

If a car has advisories related to tyres, it may require immediate replacement or repair, which can cost between £50 to £150 per tyre, depending on the make and model. Ignoring these advisories can lead to poor handling, increased stopping distances, and a higher risk of blowouts.

2. Brake Performance

Brakes are essential for safe driving, and any advisory related to brake performance should be taken seriously. Common advisories might include worn brake pads, corroded discs, or issues with brake fluid levels.

How to Spot It

During a test drive, pay attention to how the brakes feel. If they make unusual noises, feel spongy, or the car pulls to one side, these could be signs of brake issues. Additionally, check the brake fluid reservoir for low levels or contamination.

What It Means

Brake issues can lead to increased stopping distances and, ultimately, accidents. Replacing brake pads can cost between £100 to £300, depending on the vehicle. Ignoring brake advisories can lead to more severe problems, including complete brake failure.

3. Suspension Components

Suspension advisories often indicate worn or damaged components such as shock absorbers, springs, or bushings. These issues can affect ride quality and handling.

How to Spot It

Listen for unusual noises when driving over bumps, and observe how the car handles corners. If the vehicle bounces excessively or feels unstable, it may have suspension issues. A visual inspection can also reveal leaking shock absorbers or broken springs.

What It Means

Suspension repairs can be costly, ranging from £200 to £800, depending on the extent of the damage. Ignoring suspension advisories can lead to further wear on tyres and other components, resulting in even higher repair costs down the line.

4. Exhaust System

Advisories related to the exhaust system often indicate issues such as rust, leaks, or excessive noise. These problems can affect emissions and overall vehicle performance.

How to Spot It

Check for visible rust or holes in the exhaust system. Listen for unusual noises, such as hissing or rattling, while the engine is running. A strong smell of exhaust fumes inside the vehicle can also indicate a leak.

What It Means

Ignoring exhaust advisories can lead to increased emissions, potentially resulting in failing future MOT tests. Repairs can range from £100 to £500, depending on the severity of the issue. Additionally, a faulty exhaust can impact fuel efficiency and engine performance.

5. Lights and Indicators

Advisories regarding lights and indicators may seem minor but can have significant implications for safety. Common issues include dim or non-functioning lights, which can affect visibility and communication with other drivers.

How to Spot It

Check all lights, including headlights, brake lights, indicators, and fog lights. Ensure they are functioning correctly and are not dim or flickering. A simple walk-around inspection can help identify any issues.

What It Means

While replacing bulbs is generally inexpensive (around £5 to £20 per bulb), ignoring light advisories can lead to dangerous driving conditions and potential accidents. Furthermore, failing to address these issues can result in an MOT failure.

The Cost of Ignoring Advisories

Ignoring MOT advisories can lead to a myriad of problems, both in terms of safety and financial implications. While some advisories may seem minor, they can escalate into significant issues if left unaddressed. For instance, a worn brake pad can lead to damage to the brake disc, resulting in a repair bill that is several times higher than simply replacing the pads.

In addition to the direct costs of repairs, there are indirect costs to consider. A vehicle that is not roadworthy can lead to accidents, which may result in insurance claims, increased premiums, and potential legal issues. Furthermore, a car with unresolved advisories may struggle to pass future MOT tests, leading to additional costs and inconvenience.

How to Protect Yourself When Buying a Used Car

1. Conduct a Thorough Inspection

Before purchasing a used car, conduct a comprehensive inspection. Look for any advisories on the MOT history and check the vehicle's overall condition. If you are not confident in your ability to assess the car, consider hiring a professional mechanic to perform a pre-purchase inspection.

2. Obtain a Full MOT History

Request the full MOT history of the vehicle, which can be accessed online through the DVLA website. This history will provide insight into any previous advisories and whether they have been addressed. Pay close attention to recurring issues, as they may indicate deeper problems.

3. Use Vehicle Check Services

Utilise services like Vehicle Intelligence to run a free vehicle check. This can help you identify red flags instantly, including outstanding recalls, insurance write-offs, and previous accidents. Having this information can empower you to make an informed decision.

4. Negotiate Based on Advisories

If you find advisories during your inspection, use them as leverage in negotiations. Sellers may be willing to lower the price to account for the cost of repairs. Be prepared to walk away if the seller is unwilling to negotiate, especially if the advisories indicate serious issues.

5. Get a Warranty

Consider purchasing a warranty for added peace of mind. A warranty can cover unexpected repairs and provide financial protection if issues arise shortly after purchase. Ensure you understand what is covered and for how long.

Dave's Verdict — Deal-Breaker or Manageable?

In conclusion, while buying a car with MOT advisories is not inherently a deal-breaker, it requires careful consideration. Some advisories, such as minor cosmetic issues, may be manageable and easily fixed. However, critical advisories related to safety components like brakes and tyres should raise red flags and warrant further investigation.

Always approach the purchase of a used car with caution. Conduct thorough checks, understand the implications of any advisories, and don’t hesitate to walk away from a deal that doesn’t feel right. By being informed and vigilant, you can protect yourself from costly mistakes and ensure that your investment is sound.
