Buying a used car can feel like a lot to take in, what to check, what to avoid, and how to know if the car’s been looked after properly. This OakbrookAdvance guide walks you through each step, from first search to test drive, to help you make a confident choice.
Why buy a used car in 2026
Used cars continue to be a practical choice for many in 2026. They’re often available sooner than new ones and may come with smaller deposits or shorter wait times. You can choose from petrol, diesel, hybrid, or electric models across many years and trims.
With online tools like MOT history, service records, and local price comparisons, it’s now easier to check a car’s condition and get a fair deal before you buy.
1) Start with the basics online
Before arranging a viewing, take a few minutes to check:
MOT passes, fails, advisories, and mileages using the GOV.UK MOT history service
Tax or SORN status on the GOV.UK vehicle enquiry tool
Recalls using the GOV.UK recall checker
These quick checks can save you time — and help you spot cars that might not be worth the trip.
2) Choose how you want to shop
You can buy fully online, in person, or a mix of both. Online listings are convenient for viewing photos and videos, while an in-person visit lets you see the car in natural light and hear it start from cold.
Bring your phone for photos, paper towels, and clothes you don’t mind kneeling in. If possible, take a friend for a second opinion.
For reassurance, look for sellers who follow a code of practice — like Motor Ombudsman-accredited retailers, AA Cars Approved Dealers, or the RAC Approved Dealer network.
3) Walk around the car in daylight
A careful look outside can reveal a lot:
Mismatched paint or uneven gaps could mean past repairs.
Rust around arches, sills, or doors may point to longer-term issues.
Tyre tread should be above 1.6 mm (use a 20p coin to check).
Look underneath for leaks or drips.
More on tread depth is available at TyreSafe.
4) Open the bonnet and do simple checks
You don’t need tools — just a few quick looks:
Oil level between min and max, not thick or milky.
Coolant filled to the mark and clean.
Hoses should be firm, not cracked.
Battery older than five years? It may need replacing soon.
5) Sit inside and test every control
Spending a few minutes in the driver’s seat can tell you a lot:
A damp smell might mean leaks — check under the boot mat.
Try every switch: windows, mirrors, heater, air con, and radio.
When you turn the key, warning lights should appear briefly, then go out.
Not sure what a symbol means? Check the AA dashboard warning lights guide.
6) Take a meaningful test drive
If possible, start the car from cold and check:
The engine starts smoothly with no unusual noises.
Steering feels straight and brakes smooth.
Suspension feels steady over bumps.
The clutch bites mid-pedal and doesn’t slip.
Watch for excess smoke when accelerating.
This is your best chance to feel how the car really drives.
7) Check the paperwork carefully
Paperwork tells the story of how a car’s been looked after.
The V5C logbook should match the seller and car VIN.
Service history should show regular maintenance.
MOT records should match mileage and condition.

8) Confirm safety and emissions
A final check helps you stay safe and compliant:
Seatbelts should click and retract properly.
Tyres may have tread but check their date codes too.
For London drivers, check your car’s ULEZ status using TfL’s ULEZ checker.
Red flags to watch for
- Seller refuses a test drive.
Price far lower than similar cars with no reason.
Warning light stays on with excuses like “it just needs a sensor.”
