Purchasing a used car can be a smart and cost-effective way to get on the road versus buying a new motor.

However, before making such an important purchase, it’s essential to inspect every aspect of the vehicle to avoid any unexpected issues.

This Sun Motors ultimate checklist will help you navigate what to look for to ensure you always make an informed decision.

Buying a used car via Sun Motors makes the checklist experience easier, with one of their core values lying in transparency and seamlessness with some of their main features including:

• An AI function which allows for instant answers to questions about the vehicle such as “Is there any damage or accident history”, “What is the mileage” and other checklist queries
• Dealers are instantly available over WhatsApp with their emails and phone numbers also being listed on the page
• A gallery of detailed photographs of the cars and vans so that you can make your mind up before making the journey to a dealer (no time wasting)

1. Mileage

Not sure where to start? The journeys your used car has taken are a good place to begin.

One of the first things to check is the car’s mileage. A vehicle with high mileage might have more wear and tear, even if it looks great on the inside and out.

Even a car that appears well-maintained may require costly repairs if it has accumulated significant mileage over time.

Compare the mileage against the car’s age to gain a wider understanding of hidden unknowns. 

A car with average mileage (approximately 10,000 to 12,000 miles per year) typically reflects regular use.

For example, unusually low mileage could raise concerns about tampering or long periods of inactivity.

2. Documents

Before purchasing a used car, it’s important to thoroughly inspect its documents to ensure a safe and legitimate deal. 

Start with the vehicle’s logbook (V5C), MOT history and service records to ensure the Vehicle Identification Number (VIN) matches the one on the car.

For added security, you can also conduct a vehicle history check or HPI check. This reveals crucial details such as outstanding finance, accident history and previous ownership. 

Free checks online will provide limited information, however, comprehensive checks for an additional fee will provide more insights.

3. Safety features

Ensuring a car’s safety features are in good working condition is another crucial step when purchasing a used vehicle. 

Potential customers can start by inspecting features like seatbelts for any signs of fraying, damage, or improper retraction.

Airbags are equally important, look out for the airbag warning light on the dashboard; if it stays illuminated after starting the car, it could indicate a malfunction.

Next, you can check things like the anti-lock braking system (ABS). The ABS light should briefly turn on when you start the engine but go off quickly.

If it stays lit, the system may not function properly, compromising its performance during emergencies.

Never compromise on safety when buying a second-hand car. Faulty safety systems not only put you and your passengers at risk but can also lead to expensive repairs later. 

Prioritise a thorough safety inspection before buying a used car, whether you’re planning to buy from a dealership or a private seller.

4. Damage/Accident history

Always ask the seller about the vehicle’s accident or repair history, as it can reveal hidden issues.

Likewise, look closely for uneven paintwork, mismatched panels, or signs of recent bodywork, which may indicate previous damage. These inconsistencies could affect the car’s safety, performance, and resale value. 

Additionally, we’d recommend obtaining a professional inspection or a vehicle history report for extra peace of mind.

A car’s repair history is one of the most crucial parts to know about when buying a used car to avoid nasty surprises later.

Finding out a car’s history is a pivotal step in the checklist for buying a used car from a dealer.

5. Tyres

Tyres are critical to a car’s safety and performance, so a thorough inspection is essential when buying a used vehicle. 

Start by checking the tread depth; UK law requires a minimum tread depth of 1.6mm, but deeper treads are preferable for better grip and handling.

Uneven wear on the tyres could indicate alignment or suspension problems, which may require costly repairs.

Examine the tyres for cracks, bulges, or any signs of damage that could lead to a blowout. Low-quality tyres could compromise your safety and wear out faster. 

Always ensure there is a usable spare tyre or a tyre repair kit included, as these can save you from being stranded in emergencies. Well-maintained tyres enhance your safety and improve fuel efficiency.

6. Dents and scratches

While minor scratches and small scuffs will be typical for used cars, it’s crucial to take a closer look for larger dents, rust spots, or significant damage. 

These issues can go well beyond surface aesthetics and signal deeper structural problems, such as larger dents potentially indicating previous accidents or mishandling of the vehicle.

If these are left unaddressed, they could compromise the car, especially if they affect areas like doors or the frame.

Rust, on the other hand, can spread quickly and weaken the metal components of the vehicle, leading to expensive repairs. 

Pay special attention to common rust-prone areas such as wheel arches and the edges of doors and windows.

Even if the car seems well-maintained, check for recent paint jobs or filler material, as these might be used to mask rust or deeper damage.

7. Fluid Levels

Inspecting a car’s fluid levels is essential to gauge its maintenance history and overall health. 

Start off with the most important: the engine oil. It should be clean and at the correct level, dirty, sludgy oil can indicate neglect and lead to engine wear.

Checking the brake fluid is also a must, as low levels may point to leaks or worn brake components.

Examine the coolant for proper levels and clarity, cloudy or rusty coolant can signal overheating or potential radiator issues.

The transmission fluid should be clear and reddish, not dark or burnt-smelling, as this could indicate gearbox problems. Ensuring fluids are clean and adequately maintained helps you avoid a costly mechanic trip later.

8. Upholstery

Another often overlooked factor is the condition of a car’s upholstery, which can reveal how well the vehicle has been maintained.

Inspect the seats and interior surfaces for tears, stains, or unusual smells.

Persistent odours, such as smoke or mildew, can be difficult to remove and may require professional cleaning, thus costing you a trip to valet servicing.

Check for signs of excessive wear, especially on high-contact areas like the driver’s seat and armrests. Damaged upholstery not only affects the car’s appearance but can also be costly to repair or replace.

A well-maintained interior indicates the car has been looked after throughout its history.

9. Electricals

Electrical components play a significant role in a car’s functionality and comfort, so inspecting them properly is a must.

Begin by testing the basics, such as the headlights, brake lights, indicators and interior lighting. Faulty lights not only compromise safety but may also fail legal requirements.

Things like the power windows are also worth a check, ensuring they open and close smoothly without strange noises or hesitation.

Also inspect the radio, Bluetooth connectivity, and navigation features, as these can be expensive to repair or replace if they aren’t in perfect working order. 

Don’t overlook smaller electrical features like the horn, central locking, and heated seats or mirrors, if applicable.

Making sure air conditioning and climate control systems work. Faulty electrical systems could signal deeper wiring issues, which can be costly and time-consuming to fix.

10. Engine

We’ve saved the most important vessel to check until last. The engine is the heart of any vehicle, and its condition is a key factor in determining the car’s overall performance and longevity. 

When inspecting the engine, start by checking for any visible leaks, particularly around the oil filter, radiator, as well as under the vehicle. Leaks can signal potential mechanical problems that will need costly repairs.

Listening out for unusual sounds, such as knocking or grinding, could indicate engine damage or worn components.

Excessive exhaust smoke may point to engine issues like oil burning and other expensive issues.

Where possible, ask the seller to start the engine when it’s cold.

This can allow you to assess how the car performs during its initial startup. Any hesitation, rough idling, or unusual noises aren’t ideal and could indicate wider issues.
