Buying a used Subaru Legacy: what to check

These checks follow the Subaru Legacy’s own MOT record: the areas it fails on most often, and how that changes as the car gets older. None of them replaces a mechanic’s inspection, but they tell you where to look first.

The biggest drop in pass rate for the Subaru Legacy comes between 0–3 years and 3–6 years old, from 90.6% to 81.6%. If you are looking at one in or just past that range, read its MOT history closely.

By mileage, the steepest fall is from 60,000–90,000 mi to 90,000–120,000 mi: 79.5% down to 69.4%. Mileage matters as well as age, so compare the car’s recorded mileages with its year.

  1. 1. Lights and electrics

    Recorded in 66.9% of failed Subaru Legacy MOTs.

    Walk round with the lights on: headlights (dipped and main), indicators, brake lights, fog light and number-plate lamp. Check the dashboard warning lights come on with the ignition, then go out once the engine starts.

  2. 2. Suspension

    Recorded in 55.9% of failed Subaru Legacy MOTs. 22.9% of tests at 15+ years failed on suspension, against 6.3% at 0–3 years.

    Listen for knocks over bumps and speed humps, and check the car sits level. Push down on each corner: it should settle rather than keep bouncing.

  3. 3. Brakes

    Recorded in 33.3% of failed Subaru Legacy MOTs.

    On the test drive, the car should stop straight without pulling or juddering, and the handbrake should hold it on a slope. Look through the wheels for scored or heavily lipped discs.

  4. 4. Exhaust, emissions and leaks

    Recorded in 28.0% of failed Subaru Legacy MOTs. Rare on young cars, but 11.1% of tests at 15+ years failed on exhaust, emissions and leaks.

    Look under the car for fresh oil or coolant, and listen for blows or rattles from the exhaust. Watch for smoke from the tailpipe when the engine starts and when you accelerate.

  5. 5. Bodywork and corrosion

    Recorded in 20.8% of failed Subaru Legacy MOTs. 9.4% of tests at 15+ years failed on bodywork and corrosion, against 3.1% at 0–3 years.

    Look underneath and along the sills for corrosion, especially near suspension and seat-belt mountings. Uneven panel gaps or mismatched paint can indicate accident repair.

Check the car’s own MOT history. Averages describe the model, not the car in front of you. Look up its registration for past failures, advisories that were never fixed, and gaps or dips in the recorded mileage.

Ask for the service history. Invoices show what was done and when; a stamp alone shows less. See how to check Subaru service history and what a service history check can tell you.
