10 Questions to Ask When Buying a Car Privately

Buying privately can offer good value, but a private sale usually gives you fewer protections than buying from a motor trader.

The safest approach is to ask direct questions, inspect the vehicle and documents carefully, and independently verify important information before handing over money.

A vehicle-history check is useful, but it should form part of the buying process rather than replace a physical inspection, document checks or your own insurance and tax arrangements.

Here are ten practical questions to work through.

1. What Service History Does the Car Have?

Ask what service records are available and whether servicing has been carried out by a main dealer, independent garage or owner.

Evidence might include:

A stamped service book
Digital service records
Garage invoices
Receipts for parts and maintenance
Records of timing-belt, timing-chain or major component work where relevant

Do not assume that a claim of "full service history" is correct without seeing supporting records.

Compare dates and mileages in the service history with the MOT mileage record. Large inconsistencies deserve further investigation.

Different manufacturers specify different servicing schedules, so avoid assuming that every vehicle should have been serviced at one fixed annual or mileage interval.

2. Is There Any Outstanding Finance?

Ask the seller whether any finance remains attached to the vehicle, but independently verify the position before buying.

A Car Check Scotland Full Check includes an outstanding-finance check.

Outstanding finance is not included in the Basic Check.

If a finance record is returned, do not simply rely on a verbal assurance that it has been or will be settled. Ask for evidence and, where appropriate, verify the position using independently obtained contact details for the finance provider.

The legal position can depend on the type of finance agreement and the circumstances of a later private purchase. In some hire-purchase or conditional-sale situations, a private buyer who bought honestly and without knowledge of the finance may have rights known as "good title".

Because the circumstances matter, avoid treating every finance record as proof that a later private buyer will automatically lose the vehicle.

3. Has the Car Ever Been Written Off or Seriously Damaged?

Ask about previous accident damage and insurance write-offs.

A seller may know about repairs that are not recorded in vehicle-history data, so their answer still matters.

Car Check Scotland can also check recorded insurance write-off information.

Current UK insurance write-off categories include:

Category A — the entire vehicle must be crushed
Category B — the body shell must be crushed, although some parts may be salvaged
Category S — structural damage; the vehicle can return to use if repaired to a roadworthy condition
Category N — non-structural damage; the vehicle can return to use if repaired to a roadworthy condition

A repaired Category S or N vehicle may be legal to use, but its previous damage can still be important when assessing condition, value and future resale.

A history check cannot reveal every accident or repair, particularly where damage was never reported to an insurer.

4. Does the V5C Match the Vehicle and Seller's Explanation?

Private used-car buyer reviewing vehicle paperwork

Ask to see the current V5C registration certificate, commonly called the log book.

Check that:

The registration number matches the vehicle
The make and model details are consistent
The VIN on the vehicle matches the V5C
The document appears genuine
The seller can satisfactorily explain their connection to the registered keeper

The V5C identifies the registered keeper. It is not, by itself, proof of legal ownership.

A seller not being the named registered keeper does not automatically prove something is wrong, but it is a reason to ask questions and obtain a clear explanation before proceeding.

When buying, make sure you receive the correct green new-keeper slip or that the keeper change is completed through the appropriate DVLA process.

5. Does the Mileage History Make Sense?

Mileage is important when assessing a used vehicle's history, condition and value.

Check the mileage shown on the odometer against:

Previous MOT readings
Service records
Garage invoices
Older sales paperwork where available

A mileage reading increasing normally from one record to the next is reassuring, but mileage alone does not prove the mechanical condition of a vehicle.

A Basic Car Check Scotland report includes MOT mileage readings.

A Full Check adds Full mileage verification.

Investigate unexplained reductions, unusual jumps or records that use different units before making a purchasing decision.

6. What Does the MOT History Show?

Check the vehicle's current MOT status and previous MOT history.

Look at:

Pass and fail results
Recorded mileage
Major and dangerous defects
Repeated advisories
Patterns of recurring faults
The date the next MOT is due

A current MOT means the vehicle met the required test standard when it was tested.

It does not guarantee that the vehicle has no mechanical faults now, and a vehicle must remain roadworthy whenever it is used on the road.

Also check whether the vehicle has an outstanding safety recall using the appropriate manufacturer or official recall information.

7. Has the Vehicle Been Reported Stolen?

Ask the seller about the vehicle's history and independently check whether it has been recorded as stolen.

A Car Check Scotland Basic or Full Check includes a police-stolen check.

Also compare the registration, VIN and V5C carefully.

If identity details do not match, or you have reason to believe the vehicle or paperwork may be stolen, do not proceed with the purchase until the discrepancy has been properly resolved.

8. Why Is the Seller Selling the Car?

This is a simple question, but the answer can provide useful context.

Ask:

How long have you had the car?
Why are you selling it?
Are there any known faults?
Has anything recently gone wrong?
Has it recently needed major repairs?
Are there warning lights or intermittent problems?

A seller's explanation is not independent evidence, but inconsistencies between what you are told and what the documents, inspection or history show can identify areas that need more investigation.

Keep a copy of the advert and retain written messages about significant claims made before the sale.

9. Can You Inspect and Test Drive the Car?

Do not rely solely on a vehicle-history report.

Inspect the vehicle in daylight where possible and look at:

Tyres and wheels
Body-panel alignment
Paint differences
Rust and corrosion
Fluid leaks
Warning lights
Interior condition
Electrical equipment
Engine starting and running
Brakes, steering and suspension behaviour

If you are not confident assessing the mechanical condition, consider an independent professional inspection.

Only test drive the vehicle if you are legally entitled and properly insured to do so.

A vehicle-history check can identify recorded historical risks, but it cannot diagnose the engine, gearbox, brakes, suspension or every previous repair.

10. What Happens Before You Pay and Drive Away?

Before payment, make sure you are satisfied with the vehicle, seller, documents and history.

Confirm the agreed purchase price and obtain a written receipt showing appropriate details of the transaction.

Before driving the vehicle away:

Arrange your own insurance
Make sure the vehicle has a valid MOT where one is legally required
Tax the vehicle yourself before using it on the road
Complete the keeper-change process
Keep your purchase receipt and relevant correspondence

The seller's road tax does not transfer to you.

The seller's motor insurance does not automatically become your insurance.

Do not treat the V5C as proof that the person selling the vehicle necessarily owns it.

What a Vehicle-History Check Can and Cannot Tell You

A Car Check Scotland vehicle-history report can help verify recorded information, but the coverage depends on the report level.

A Basic Check includes key vehicle information together with MOT and tax information, MOT mileage readings, a police-stolen check and an insurance write-off check.

A Full Check includes everything in Basic and adds outstanding finance, Full mileage verification and further vehicle-history information.

A vehicle-history report does not replace a physical or mechanical inspection.

It may not reveal:

Mechanical faults
Every unreported accident
Hidden corrosion
Poor-quality repairs that were never formally recorded
Current tyre or brake condition
Interior damage
Every developing electrical fault

Use the report alongside the vehicle, its paperwork and the seller's answers.

Conclusion

A private used-car purchase deserves more than a quick look around the vehicle and a handshake.

Ask all ten questions, verify important answers independently and investigate anything that does not add up.

Check the V5C and VIN, study the MOT and mileage history, ask about servicing and damage, check stolen and write-off information, and use a Full Check when you need outstanding-finance information.

Before driving away, arrange your own insurance and tax the vehicle yourself.

Frequently Asked Questions

What checks should I do before buying a car privately?

Check the vehicle's identity and V5C details, MOT history, mileage, service records and physical condition. Ask about previous damage and known faults. Use a vehicle-history check for recorded information such as stolen and write-off status, and use a Full Check where you need outstanding-finance information.

Does the V5C prove the seller owns the vehicle?

No. The V5C records the registered keeper and is not, by itself, proof of legal ownership. Check that the vehicle and document details match and ask for an explanation if the person selling the vehicle is not the registered keeper.

How do I check whether a car has outstanding finance?

A Car Check Scotland Full Check includes an outstanding-finance check. If finance is recorded, investigate it carefully and obtain appropriate evidence before proceeding. The legal consequences can depend on the agreement and circumstances, including whether a private buyer may have good-title rights.

Does an MOT prove a used car is mechanically sound?

No. An MOT records whether the vehicle met the required test standard when it was tested. It does not guarantee the vehicle's present mechanical condition or remove the need for an inspection.

Do the seller's tax and insurance transfer to me?

No. The buyer must arrange their own insurance and tax the vehicle before using it on the road.

Is a vehicle-history report enough on its own?

No. A vehicle-history report checks recorded information. It does not diagnose mechanical faults or reveal every unreported accident or repair, so combine it with document checks and a physical inspection.
