Should I check the MOT history before buying a 2017 BMW 125?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2017 BMW 125?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2017 BMW 125?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Moderate sample. 408 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2017 BMW 125 punches well above the UK average with a 90.8% first-time pass rate compared to 80% nationally, but the headline is tempered by a concerning 33.8% of vehicles having experienced a dangerous defect at some point—well above acceptable thresholds and a genuine buyer red flag. Petrol and diesel variants perform nearly identically (91.2% and 90.6% respectively), so fuel choice won't be a reliability differentiator here.

With a median mileage of 52,124 miles for a seven-year-old car, these examples are running at typical wear levels, yet they're racking up 4.7 advisories on average and 0.75 failures per test, suggesting routine maintenance costs and component replacements are baked into ownership. Before buying, have a pre-purchase inspection focus specifically on the braking system and suspension—the dangerous defect rate hints at structural or safety weaknesses that MOT passes can mask.

The 2017 BMW 125 has a decent first-time pass rate (90.8%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ 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.

For context

✅ Good baseline reliability. A 90.8% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 4.7 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 408 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.

Watch for defects — worth knowing

What tends to go wrong

Across 408 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Tyre wear 35.4%

Offside Rear Tyre worn close to legal limit/worn on edge · Nearside Rear Tyre worn close to legal limit/worn on edge · Offside Front 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 28%

Rear Brake pad(s) wearing thin · Front Brake pad(s) wearing thin · Front Brake disc worn, pitted or scored, but not seriously weakened · …

Ask the seller when brakes were last serviced. If they don't know, factor in the cost.

Other issues 13.3%

COVID-19 6 MONTH EXTENSION · Windscreen damaged but not adversely affecting driver's view · Nearside Rear Child Seat fitted not allowing full inspection of adult belt

Lighting 6.6%

Nearside Front Road wheel slightly distorted

Usually cheap to fix. Worth confirming all lights work before collecting.

Suspension & steering 6.5%

Nearside Front Shock absorbers has light misting of oil

Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.

Half of all 2017 BMW 125 vehicles fall between 41,932 and 63,611 miles.

Is the mileage you're seeing normal?

✓ 41,932–63,611 miles — normal for age. This is where most 2017 BMW 125s sit.

Almost all 2017 BMW 125s are still on the road.

Strong survival — 381 vehicles still getting MOTs in 2025, 96% of the peak.

Based on vehicles from this manufacture year that had at least one MOT test in each calendar year. Data from 2019–2025.
* The 2020 dip reflects the government's COVID-19 MOT exemption, which allowed certificates to be extended by six months — fewer tests were conducted that year.
