Should I check the MOT history before buying a 2003 MG Tf?

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.

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.

The 2003 MG TF's 72.2% first-time pass rate trails the UK average by nearly 8 percentage points, signalling above-average reliability concerns. More worryingly, 38.6% of these cars have suffered a dangerous defect at some point, making this a genuine safety consideration for any buyer.

At 47,200 miles average, these TFs show relatively modest mileage for their age, yet they're accumulating 4.63 failures and 20.8 advisories per vehicle on average—suggesting mechanical fragility rather than just age-related wear. Before purchase, budget for prompt attention to any advisory items, and expect to spend time and money on repairs more frequently than you would with a more reliable modern classic.

The 2003 MG Tf has a below-average first-time pass rate (73.3% 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 20.8 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 9,315 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.
