This 2001 Cadillac Seville comes out swinging at a reliability concern: its 72.1% first-time pass rate sits 7.9 points below the UK average, and nearly 22% of these vehicles have recorded dangerous defects—a meaningful risk flag for a buyer. The low pass rate is consistent across the petrol models (71.3%), so fuel type isn't the issue here.

These Sevilles are running around 63,500 miles at median age, which is reasonable for a 23-year-old car, but they're racking up 2.5 failures and a hefty 15 advisories per test—suggesting persistent wear issues rather than catastrophic failures. Before committing to one, get a pre-purchase inspection focused on suspension, brakes, and electrical systems, since advisory counts this high typically point to accumulated component degradation in older American luxury cars.
