Finding cars that start with the letter O feels like a weird scavenger hunt. You’d think with all the brands out there, the alphabet would be a bit more generous, but honestly, it’s a sparse landscape. Most people immediately jump to Oldsmobile or Opel, and then their brain just... stalls. It's kinda funny. We have thousands of models across a century of automotive history, yet the "O" section of the catalog is surprisingly lean.
But lean doesn't mean boring.
If you're a car enthusiast or just someone trying to win a very specific trivia night, the variety here is actually wild. You have American heavyweights that defined the muscle car era, quirky European hatchbacks that never quite made it across the pond, and high-end exotics that most of us will only ever see in a YouTube video.
The Heavy Hitters: Oldsmobile and Opel
You can't talk about cars that start with the letter O without starting with the big guys. Oldsmobile is the one everyone knows, or at least your dad does. Founded by Ransom E. Olds in 1897, it was a cornerstone of General Motors for over a century. They weren't just "old people cars" either. The Oldsmobile 88 basically birthed the muscle car movement with its Rocket V8 engine in 1949. It was fast. It was loud. It was exactly what post-war America wanted.
Then you have the Cutlass. In the 1970s and 80s, the Cutlass wasn't just a car; it was the car. It topped sales charts for years because it hit that sweet spot of luxury and affordability. People loved that plush, velvet-adjacent upholstery and the smooth ride that felt like floating on a cloud. It's a shame GM pulled the plug on the whole brand in 2004, but the legacy of the 442 and the Toronado—the first front-wheel-drive American car since the 1930s—remains legendary.

On the other side of the Atlantic, we have Opel.
Now, if you live in the UK, you know them as Vauxhall. If you're in the US, you probably drove an Opel and didn't even realize it. For decades, Buick rebranded Opel models like the Regal (originally the Opel Insignia) or the Cascada. Opel has this reputation for building sensible, "bread and butter" cars, but they've had some real gems. The Opel Manta is a cult classic, a sleek coupe that looked like a mini muscle car. Then there’s the Opel GT, which basically looks like a baby Corvette. It had those cool manual pop-up headlights that you had to rotate with a lever in the center console. Talk about tactile.
The Modern Oddities and Supercars
While the big brands take up most of the oxygen, the "O" category gets weirdly interesting when you look at niche manufacturers and specific models. Take Oreca, for example. You won't see these at a local grocery store. Oreca is a French racing team and constructor that builds some of the most successful prototypes for the 24 Hours of Le Mans. If you've ever watched endurance racing, you've seen an Oreca 07 flying down the Mulsanne Straight. It’s pure function over form, carbon fiber everything, and a noise that rattles your teeth.
Then there’s the exotic stuff.

The Okuyama design house, led by Ken Okuyama (the guy who designed the Ferrari Enzo), produced the Kode57 Enji. It’s a stunning open-top speedster that looks like it belongs in a sci-fi movie. It's rare. It's expensive. It’s exactly what car enthusiasts drool over.
And we can't forget the models themselves. While we're talking about cars that start with the letter O, we have to mention the Honda Odyssey. It’s the king of the "dad-mobile." It might not be "cool" in the traditional sense, but anyone who’s had to haul three kids and a Golden Retriever to a soccer game knows the Odyssey is a masterpiece of engineering. Between the built-in vacuum cleaners (in older models) and the Magic Slide seats, it’s basically a living room on wheels.
A Quick Look at the "O" Names You Forgot
- Ogle: A British firm from the 60s. They made the SX1000, based on the Mini, which looked way faster than it actually was.
- Osella: An Italian racing outfit that briefly dabbled in Formula 1. They weren't very successful, but hey, they were there.
- Otomo: A super obscure Japanese car from the 1920s. Good luck finding one of those at a Cars and Coffee.
- Overland: This was the precursor to Willys-Overland, which eventually gave us the Jeep. Without Overland, the off-roading world would look very different today.
Why the Letter O Matters for Collectors
For collectors, "O" cars offer a unique opportunity. Because brands like Oldsmobile are defunct, the market for them is relatively stable. You can pick up a clean 1970s Cutlass for a fraction of what a Chevelle or a Charger would cost, even though they share a lot of the same DNA. There’s a sense of nostalgia there that’s hard to replicate.
Opel, too, is seeing a bit of a resurgence in the enthusiast community. The Manta and the GT are becoming increasingly popular for Restomod projects. People are swapping in modern Ecotec engines or even electric powertrains into these lightweight vintage shells. It’s a way to keep the "O" lineage alive while making them daily-drivable in the 2020s.

Let’s be real: most people don't go looking for cars that start with the letter O unless they're doing a crossword or searching for a specific vintage vibe. But once you dig in, you realize it’s a category full of innovators. From the first high-compression V8s at Oldsmobile to the precision aerodynamics of an Oreca chassis, these cars have shaped the industry in ways that aren't always obvious.
Actionable Insights for Your "O" Car Journey
If you’re looking to buy, restore, or just learn more about this specific corner of the automotive world, here is how you should actually approach it:
- Check the GM Parts Bin: If you’re buying a vintage Oldsmobile, remember that many mechanical parts are shared with Chevy, Pontiac, and Buick. This makes maintenance much easier and cheaper than people think.
- Look for Rebranded Models: If you love European handling but live in North America, look at Buick models from 2010-2020. Many are literally Opels with a different badge. You get the German engineering without the "import" repair prices.
- Research the "O" History of Jeep: If you're a 4x4 fan, look into the history of Overland. Understanding the transition from Overland to Willys gives you a much deeper appreciation for the heritage of the Wrangler.
- Join Niche Forums: Because "O" brands are often defunct or specialized, the best information isn't in manuals—it's in the heads of long-time enthusiasts. Sites like ClassicOldsmobile.com are gold mines for technical advice.
- Don't Sleep on the Odyssey: If you need a family hauler, don't let the "minivan" stigma stop you. The Honda Odyssey has some of the best resale value in the entire industry for a reason.
The world of cars starting with the letter O isn't the biggest, but it’s definitely one of the most diverse. Whether it's a screaming race car or a plush 70s cruiser, there's a lot more under the hood than just a single letter.
