CAR4 FIELD GUIDE / 01

Take your time. Check everything. Be willing to leave.

01

How to choose a used car

Begin with your real weekly use, not a dream specification. Set a total budget that leaves room for tax, insurance, immediate servicing, and an unexpected repair. Shortlist models with a good supply of examples and independent parts support.

02

What to check before buying

View the car in daylight and when the engine is cold. Look for uneven panel gaps, mismatched paint, tire wear, warning lights, leaks, damp carpets, and signs that wear does not match the recorded mileage.

Car4 note

If the car matters enough to buy, it matters enough to inspect independently. A pre-purchase inspection can be money well spent.

03

Questions to ask the seller

Ask how long they have owned it, why they are selling, what has recently been repaired, whether it has been in an accident, and if any finance remains. Clear, consistent answers matter as much as the words themselves.

04

Common red flags

Be cautious of a warm engine on arrival, missing history, rushed viewings, payment pressure, inconsistent vehicle details, fresh underseal, warning lights that fail to illuminate, or a seller who will not let you inspect independently.

05

Test drive checklist

Drive on mixed roads. Check cold starting, clutch or transmission behavior, steering alignment, braking, suspension noise, engine temperature, visibility, and every major control. The car should track straight without vibration or warning lights.

06

Documents to check

Match the vehicle identification number in several locations, verify registration and ownership details, review service records and invoices, check inspection history, and run an appropriate history and outstanding-finance check.

Frequently asked

Used car questions

Should I inspect a used car when the engine is cold?

Yes. A cold start can reveal battery, starter, smoke, noise, and rough-running issues that may be hidden once an engine is warm.

Is a vehicle history check enough?

No. It is a useful background check, but it cannot replace a careful physical inspection, test drive, document review, and independent mechanical assessment.

When should I walk away from a used car?

Walk away when details do not match, the seller prevents reasonable checks, important documents are missing, or you feel pressured to decide before you are comfortable.
