Should I check the MOT history before buying a 2017 BMW 5 Series?

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 5 Series?

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.

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.

The 2017 BMW 5 Series is more reliable than average, with a 90.8% first-time pass rate well above the UK average of 80%, and petrol and diesel variants perform nearly identically at around 91%. However, one in four vehicles (25.3%) have had a dangerous defect flagged during MOT, which is a genuine concern for buyers and worth investigating on any used example you're considering.

At 56,000 miles median for a seven-year-old car, these 5 Series have been sensibly driven, and the 0.71 average failures per vehicle suggests major problems are rare once you find one that passes. The 4.5 advisories per car point to typical wear on suspension, brakes and minor trim items rather than structural weakness—so budget for routine maintenance, but don't expect catastrophic repair bills; on purchase, have a pre-buy inspection done by a BMW specialist to verify the dangerous defect history hasn't been buried.

The 2017 BMW 5 Series 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 4.5 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 15,370 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.
