The bottom line
Cadillacs need a ruthless engine check first. Oil leaks hit more than half, usually alongside fuel-trim issues and dirty oil, so pressure-test for leaks and scan for codes before anything else—walk if either looks active. Electronics faults pile on almost as frequently, and these cars fall below decent condition earliest of all brands, around 76,000 miles. Hunt the lowest-mileage ones still available, treat any deferred service as negotiation ammo, and be ready to walk rather than inherit someone else's neglected powertrain.
