The 2013 MG 3 passes its MOT first time in 79.4% of cases, marginally below the UK average of 80%, but the real concern is that 36.3% of vehicles in this cohort have recorded a dangerous defect at some point—well above what you'd expect. This suggests reliability issues that go beyond routine wear and tear.

With a median mileage of just 39,155 miles for a 2013, these cars are relatively lightly used, yet they're still racking up an average of 2.55 failures and 15 advisories per vehicle. Before buying, request the full MOT history and get any vehicle independently inspected, paying particular attention to the systems that have triggered dangerous defects in the past.

We have limited data for the 2013 MG 3 — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

Watch for defects — worth knowing

What tends to go wrong

Across 146 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Tyre wear 47.2%
Offside Front Tyre worn close to legal limit/worn on edge · Nearside Front Tyre worn close to legal limit/worn on edge · Nearside Rear Tyre worn close to legal limit/worn on edge · …
Budget for a full set — on a vehicle this age, tyres are expected consumables. An inspection will confirm how much is left.
Brake wear 41.9%
Front Brake pad(s) wearing thin · Front Brake disc worn, pitted or scored, but not seriously weakened · Nearside Front Brake pipe corroded, covered in grease or other material · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Lighting 38.4%
Supplementary restraint system warning lamp indicates a fault
Usually cheap to fix. Worth confirming all lights work before collecting.
Suspension & steering 34.5%
Offside Front Suspension arm pin or bush worn but not resulting in excessive movement · Nearside Front Suspension arm pin or bush worn but not resulting in excessive movement
Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.
Other issues 24.7%
Front Sub-frame corroded but not seriously weakened · Oil leak, but not excessive
