Should I check the MOT history before buying a 2023 BMW 520i M Sport MHEV Auto?

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 2023 BMW 520i M Sport MHEV Auto?

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.

Do I need an HPI check when buying a 2023 BMW 520i M Sport MHEV Auto?

Too new to rate yet — worth knowing

Got a specific BMW 520i M Sport MHEV Auto you're checking out?

The real detail is in the individual vehicle report — MOT history, AI Hunches, mileage timeline, and defect patterns for that specific reg.

This 2023 BMW 520i is exceptionally reliable by UK standards, with a 97.1% first-time MOT pass rate that sits well above the 80% national average—dangerous defects are virtually non-existent at just 1.1% of vehicles. The average car has seen only 0.01 failures and 0.1 advisories per test, suggesting these are genuinely well-built examples with minimal wear issues so far.

At a median mileage of just over 19,000 miles for a 2023 model, these cars are still very young and lightly used, which partly explains the strong MOT results. When you're looking at one, focus on service history and whether it's been regularly maintained—that low failure rate won't last if you skip the BMW dealer schedule, so confirm all services are stamped before you buy.
