Mannix, the iconic TV private investigator from the 1960s and 70s series, drove a series of classic American convertibles. The most frequently associated car is the 1969 Dart GTS convertible. However, the show famously provided him with a new car each season after his current one was inevitably destroyed in chase scenes, making his ride a rotating showcase of late-60s/early-70s Detroit muscle.
The primary vehicle was the '69 Dart GTS, but he also drove models like the 1970 and 1971 Dart Swinger 340s. These cars were central to the show's action-packed identity. The Dart GTS was a potent muscle car in its own right, often equipped with a 340 cubic inch V8 engine. This engine produced around 275 horsepower, giving Mannix the power needed for his high-speed pursuits. The car's rugged chassis and relatively lightweight body made it a capable handler for the era.
| Model Year | Make & Model | Engine | Notable Episode / Context |
|---|---|---|---|
| 1969 | Dodge Dart GTS Convertible | 340 cu in V8 | Primary car for season 2, often destroyed in chases. |
| 1970 | Dodge Dart Swinger 340 | 340 cu in V8 | Featured in season 3, a hardtop model. |
| 1971 | Dodge Dart Swinger 340 | 340 cu in V8 | Used in later seasons, recognizable by its new grille. |
| 1968 | Oldsmobile 442 | 400 cu in V8 | Briefly driven in the first season before the Dodge partnership. |
| 1967 | Plymouth Barracuda | 383 cu in V8 | Appeared in a first-season episode. |
The constant destruction of these vehicles was a unique and memorable gimmick. It was a brilliant piece of product placement for Chrysler, which supplied the cars to the show. For viewers, it became a fun anticipation at the start of each season to see what new model Mannix would be driving before it met its dramatic end. This rotation makes citing just one car as "the" Mannix car slightly inaccurate, though the 1969 Dodge Dart GTS remains the most iconic.

Oh, that’s easy. He drove a Dart. It was always a convertible, and it was always getting smashed up in these crazy car chases. I loved that show as a kid. Every season, you’d wait to see what color the new one would be. It was usually a tan or green GTS model. That car was a real part of his character—tough and classic, just like him.

As a car guy, the Mannix car is a fascinating case study in 70s muscle. It wasn't just one car; it was a fleet of Darts, primarily the GTS and Swinger 340 trims. The 340 cubic inch V8 was the star. It wasn't the biggest engine, but it was a lightweight, high-revving package perfect for TV chases. The show was a masterclass in automotive product placement, showcasing Chrysler's performance lineup through spectacular, scripted destruction.

From a collector's standpoint, the Mannix Darts are television history. The most valuable would be a 1969 GTS convertible, identical to the season-two car. Its value isn't just in its specs but in its pop-culture status. While many were stunt cars destroyed filming, any surviving '69-'71 Dart convertible now carries a "Mannix" premium. It’s a piece of Americana, representing a specific era of detective shows and American automotive design.

I remember it being a cool, sporty convertible, but the wildest part was that they wrecked it all the time. My dad would joke that the car chases were the best part of the show. It definitely wasn't a fancy European car; it was a solid, good-looking American machine. That detail of getting a new one each year really stuck with me. It made the show feel more exciting and unpredictable than others on TV at the time.
