Why buyers get caught
The big mistake is buying the spec and missing diesel DPF/EGR risk, timing or oil-service issues, gearbox behavior, rust, and brake problems.
Common problems to check
Diesel DPF and EGR faults
Diesel cars need use-pattern evidence, warning-light history, and clear emissions repair records.
Timing and oil-service sensitivity
Long intervals, low oil, chain noise, or turbo symptoms deserve caution.
Manual or automatic gearbox wear
Clutch slip, judder, harsh shifts, or flare should be checked on a proper drive.
Brakes, EPB, and suspension
Electronic parking-brake faults, seized calipers, knocks, and uneven tyres affect ownership cost.
Rust, water leaks, and infotainment
Arches, underside, boot dampness, camera, screen, and Bose faults should be checked.
Ask before you travel
- Petrol or diesel, and what is the driving pattern?
- Any DPF, EGR, turbo, timing, or oil-pressure history?
- Any gearbox, clutch, brake, or EPB repairs?
- Any rust treatment or body repair?
Discount hard or walk away if
- Diesel warnings with no invoices.
- Oil or timing symptoms.
- Rust hidden by fresh paint.
- EPB or brake faults ignored by seller.
