Rover 75 (2004)

14,529 real MOT outcomes analysed • 73.8% first-time pass rate

2004 Rover 75

CarHunch analysed 14,529 real MOT records for the 2004 Rover 75. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2004 Rover 75's first-time pass rate of 73.8% trails the UK average of 80% by a meaningful margin, and nearly a third of these cars have recorded dangerous defects at some point—a significant concern for a buyer. The diesel variant performs worse still at 71.9% pass rate compared to petrol's 76.2%, suggesting the diesel engines in this generation have aged less gracefully.

These cars are typically running around 87,500 miles at test time, which is reasonable for their age, but the average of 4.32 failures per vehicle reveals fundamental structural or mechanical issues beyond routine wear. If you're considering one, budget for serious remedial work: with 22.4 advisories per car on average, the nicest examples will still need attention to brakes, suspension, and electrics—get a full pre-purchase inspection and factor in £1,500+ for deferred maintenance.

What to check before buying a 2004 Rover 75

Practical pre-purchase checks for this age and model.

  • 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
  • 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
  • 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
  • ⚠️ 31.2% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
