Buying a used Toyota GR Yaris: what to check
These checks follow the Toyota GR Yaris’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.
By mileage, the steepest fall is from 0–30,000 mi to 30,000–60,000 mi: 96.4% down to 89.7%. Mileage matters as well as age, so compare the car’s recorded mileages with its year.
1. Tyres
Recorded in 57.6% of failed Toyota GR Yaris MOTs.
Check tread depth across the whole width of every tyre, including the inner edge. Uneven wear can point to alignment or suspension problems. Look for cuts and bulges in the sidewalls.
2. Lights and electrics
Recorded in 15.9% of failed Toyota GR Yaris 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.
3. Number plates and VIN
Recorded in 14.6% of failed Toyota GR Yaris MOTs. Rare on young cars, but 1.2% of tests at 3–6 years failed on number plates and vin.
Match the registration plates and the VIN (usually at the base of the windscreen and on a door pillar) to the V5C.
4. Exhaust, emissions and leaks
Recorded in 14.3% of failed Toyota GR Yaris MOTs.
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. Windscreen and wipers
Recorded in 12.1% of failed Toyota GR Yaris MOTs.
Look for windscreen chips and cracks in the driver’s line of sight, and check the wipers clear the screen and the washers work.
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 Toyota service history and what a service history check can tell you.
