The 2003 Bentley Arnage passes its MOT first time at 87%, which is a solid 7 percentage points above the UK average—but a fifth of these cars have recorded dangerous defects, so mechanical integrity deserves close inspection before purchase. Petrol vs diesel breakdowns aren't available for this model, but the headline reliability picture is encouraging relative to the national benchmark.
At 20,000 miles above the UK median for its age, the average Arnage in this cohort has seen moderate use, yet it's racking up 2.5 failures and nearly 11 advisories per test—a sign that keeping one running costs money and attention. Before committing, budget for specialist servicing and get a pre-purchase inspection focused on the electrical and suspension systems, where advisory trends typically cluster on this model.
