Lexus Sc430 (2006)

228 real MOT outcomes analysed • 84.1% first-time pass rate

2006 Lexus Sc430

CarHunch analysed 228 real MOT records for the 2006 Lexus Sc430. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2006 SC430 passes its MOT at 84.1%, comfortably ahead of the UK average of 80%—but that headline masks a serious concern: 32% of these cars have recorded at least one dangerous defect during their MOT history, well above the threshold that should worry a buyer. Petrol-only powertrain means no diesel trade-off to consider here.

At an average mileage of 56,116 miles, these 18-year-old cars are running relatively low, yet they average 3.11 failures and 16.4 advisories per test, suggesting age-related wear dominates over mileage. Before buying, request the full MOT history and have an independent specialist inspect the brakes, suspension, and convertible roof mechanisms—these high-mileage luxury cars demand it.

What to check before buying a 2006 Lexus Sc430

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.
  • ⚠️ 32% 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.
