Reliability, what owners report, and what it costs to keep.
AVOIR's read: the numbers are mixed and the complaint record is worth reading before you commit.
Owners have filed 48 complaints with NHTSA about the 1993 Cadillac Eldorado, and it carries 2 recalls. These are owner allegations rather than confirmed defects, but the pattern of what people complain about is the most useful signal a used buyer has.

NHTSA lists 2 recall campaigns for the 1993 Cadillac Eldorado. Recalls are free to have fixed at a franchised dealer regardless of who owns the car now, but only if they were never done, so check the VIN of the specific car rather than trusting the model.
THE FUEL FEED AND RETURN LINES TO THE ENGINE FUEL INJECTION SYSTEM WERE NOT FULLY ASSEMBLED AND LOCKED. THE LINES CAN WORK LOOSE, CAUSING A FUEL LEAK IN THE ENGINE COMPARTMENT.
Risk: FUEL LEAKS IN THE ENGINE COMPARTMENT CAN RESULT INUNDERHOOD FIRES IF EXPOSED TO A SOURCE OF IGNITION.
Fix: DEALER WILL INSPECT VEHICLE AND, IF NECESSARY, ADJUST OR REPLACE THE FUEL FEED AND RETURN LINES TO THE ENGINE FUEL INJECTION SYSTEM.
IF THE AIR CONDITIONER COMPRESSOR CLUTCH ASSEMBLY CONTACTS THE AUXILIARY ENGINE OIL COOLER OUT HOSE, THE HOSE MAY WEAR THROUGH ALLOWING ENGINE OIL TO LEAK IN THE ENGINE COMPARTMENT.

What stands behind each score for this car:
Owners have filed 48 complaints with NHTSA for this model-year, and engine and engine cooling is the most reported area with 12 of them (25%). There are 2 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 82/100 (excellent) from NHTSA recall campaigns and complaint density. That figure is a raw complaint count, not yet adjusted for sales volume, so a high-volume model scores worse than it deserves.
AVOIR scores its longevity 76/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 1993 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: be careful, because the numbers are mixed and the complaint record is worth reading before you commit. Its overall ownership score is 66/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
