Should I check the MOT history before buying a 2003 Lexus Gs430?

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.

The 2003 GS430 has an 82% first-time pass rate, marginally above the UK average of 80%, which suggests broadly decent reliability—but the 35.1% of cars that have recorded dangerous defects is a genuine concern and warrants a pre-purchase inspection by a specialist. These vehicles typically show 3.63 failures and 21.4 advisories per test, indicating aging components that need monitoring rather than outright failures.

At 78,433 miles median for a 21-year-old car, these examples are relatively well-preserved, suggesting owners have treated them reasonably. Before buying, get a full diagnostic check on the suspension, electrical systems, and cooling components—the advisory count hints at wear accumulating in these areas—and budget for maintenance of this Japanese luxury sedan's more complex systems.
