Should I check the MOT history before buying a 2002 MG Zr?

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 2002 MG Zr?

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 2002 MG Zr?

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 2002 MG ZR falls well short of the UK average with a 69.8% first-time pass rate, meaning nearly a third of these cars fail their MOT—and one in five has suffered a dangerous defect, a genuine safety concern for buyers. Petrol and diesel variants perform almost identically, both around 70%, so fuel type won't be a deciding factor in reliability.

These ZRs are averaging 62,858 miles—reasonable for a 22-year-old car—but they're racking up 3.4 failures and 9.3 advisories per vehicle, signalling widespread wear across multiple systems rather than one weak spot. Budget for repairs and have any ZR you're considering given a thorough pre-purchase inspection, because the numbers suggest these cars require consistent maintenance to stay roadworthy.

The 2002 MG Zr has a below-average first-time pass rate (71.9% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ 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

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 9.3 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 12,337 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.

Based on vehicles from this manufacture year that had at least one MOT test in each calendar year. Data from 2014–2024.
* 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.
