Oldsmobile
“[The Cutlass is] more popular than its division stablemates largely because of styling, nicer interior appointments, and Oldsmobile’s durability reputation.”

- Cutlass: “No significant problem areas, [though Colonnades] not a paragon of space utilization, but adequate for a typical family.” CG rating: 2-3
- Cutlass (downsized): “Above-average for reliability, except for ’79 V6s, which rate average.” CG rating: 4
- Delta 88/Ninety-Eight: “Main drawbacks here are excess size and weight, which penalize fuel economy and maneuverability. Frequency-of-repair rate lower-than-average except for 1974 models.” CG rating: 3
- Delta 88/Ninety-Eight (downsized): “Many virtues including roomy interior, high ride comfort, big trunk, and low noise levels. Question: wouldn’t a Cutlass fit your needs just as well?” CG rating: 4
- Omega: “While we see no reason to buy the Omega over its cheaper [corporate siblings], we praise Omega’s overall good repair history.” CG rating: 2-3
- Omega (1980): “A fine used car buy for the 1980s.” CG rating: N/A
- Starfire: “The problem in taking a single GM car and spreading it throughout each of the divisions is that when the design is bad, the corporation gets not one black eye but several. This is the case with the Oldsmobile Starfire.” CG rating: 2
- Toronado: “An automobile that has a superior repair record cannot receive a poor used-car rating. But that is the only thing preventing us from ranking the Toronado lowest in the personal luxury class.” CG rating: 2
- Toronado (downsized): “A welcome return to sanity in design, fuel economy, ride, and handling.” CG rating: N/A
