The bottom line
Cadillacs tend to show their age through the engine bay more than anything else. Fuel-trim problems and oil leaks hit more than half the cars, often paired with active codes and neglected oil, so start every inspection there and walk if leaks are active or trims are wildly off. Longevity ranks dead last—these typically drop below decent condition around 86,000 miles—so favor lower-mileage examples and treat anything past that mark as a hard negotiation lever or a pass unless the service records are airtight.
