The 2005 Lexus GS430 passes its MOT at 82.5%, marginally above the UK average of 80%, which is respectable for a nearly 20-year-old car—but the red flag here is that 40.6% of these vehicles have recorded a dangerous defect at some point, well above the typical concern threshold. This suggests structural, brake, or steering issues are notably common in the model and warrant a thorough pre-purchase inspection.

At around 76,600 miles median, these cars are running lower than typical for their age, which is a positive sign of careful ownership, yet they still average 3.25 failures and a heavy 17.4 advisories per test cycle. Before committing to one, insist on a full diagnostic check focusing on suspension, brakes, and steering geometry—the dangerous defect history points to these as the real weak spots rather than engine issues.

We have limited data for the 2005 Lexus Gs430 — treat the figures below as indicative rather than definitive.

⚠️ 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.
