Why this vehicle matters
The Cutlass Supreme was America's favorite car in the mid-1970s — not a Chevy, not a Ford, but an Oldsmobile. The Colonnade body introduced in 1973 hit exactly the right note of personal luxury: formal rooflines, opera windows, comfortable interiors, and enough engine options to satisfy most tastes. The 1976 model year was peak Cutlass, selling over 500,000 units. These were the cars parked in suburban driveways across America, the cars driven to disco and back, the cars that defined malaise-era comfort. Today, they're finally getting respect as survivors of an underappreciated era.
Patina notes
Cutlass Supremes in honest, preserved condition are increasingly valued. The Colonnade styling ages gracefully. Many were optioned heavily — look for interesting configurations like the Salon package or Hurst/Olds equipment. Vinyl tops were popular and often hide rust underneath. Low-mile survivors exist because these were often purchased by older buyers who drove them carefully.
Ownership reality
Excellent parts availability through GM A-body channels. The 350 and 455 Oldsmobile engines are reliable and well-documented. Mechanical simplicity makes DIY maintenance practical. These cars ride and drive well by period standards — they were comfortable then and remain comfortable now. The challenge is finding one that wasn't used up; many were daily drivers that accumulated miles and deferred maintenance.
The verdict

You want affordable personal luxury nostalgia. You appreciate the Colonnade era. You like having the best-selling car of its year.

1966 Oldsmobile Toronado
The Toronado was audacious: a full-size personal luxury car with front-wheel drive, at a time when the only other FWD cars in America were imports. GM's engineers developed a unique split drivetrain — the engine sits behind and above the transmission, connected by a chain to the torque converter. It worked, and worked well enough to win Motor Trend's Car of the Year. The dramatic fastback roofline and hidden headlights made it look like nothing else on the road. The Toronado proved that Oldsmobile was willing to take engineering risks that other GM divisions wouldn't touch.
1970 Oldsmobile 442
The 442 was Oldsmobile's answer to the GTO, and by 1970 it had evolved into a legitimate muscle car heavyweight. The 455 V8 made a stump-pulling 500 lb-ft of torque. The W-30 package added Ram Air induction, a hotter cam, and an aluminum intake — the fastest Oldsmobile you could buy. The '70 redesign gave it swoopier lines that aged better than some competitors. 'Dr. Oldsmobile' ads positioned it as the prescription for boring transportation. The 442 name originally meant 4-barrel carb, 4-speed manual, and dual exhaust — by 1970 it had become its own model designation.
