A blue convertible sits with its top down, its E-body lines unmistakably Mopar — but the year and engine are left for you to figure out. Plymouth built only 635 ‘Cuda convertibles in this model year, and a rare few carried an engine option that turned them into million-dollar auction stars. Everything else stayed a well-loved cruiser worth a fraction of that. Take a guess before the details give it away.
This one hides behind a color that Mopar collectors either love or can’t stand — and that’s exactly the point. The convertible top is down, the stance is low, and everything about the silhouette says muscle car royalty, but the specific year and drivetrain underneath separate a six-figure legend from a car worth a fraction of that. Plymouth built shockingly few of these topless E-body cars in this particular model year, and even fewer with the engine that turns heads at auction. Squint at the grille and taillight details before you guess, because getting the year wrong here isn’t a small miss — it changes the value by a factor of ten. What’s actually hiding under that hood?

A Convertible Rarer Than Most Realize
This is a 1970 Plymouth ‘Cuda convertible, one of just 635 built for the entire model year across every engine option. Plymouth’s E-body platform launched in 1970 to take on the Mustang and Camaro directly, and the convertible variant was always the rarest body style — buyers overwhelmingly chose the hardtop. That scarcity alone makes any 1970 ‘Cuda ragtop a desirable find today, regardless of what’s under the hood.
The Engine That Changes Everything
Engine choice is what separates a nice classic from a seven-figure collectible. Plymouth only built 14 Hemi ‘Cuda convertibles for 1970, plus 34 more with the 440 Magnum V8 — a combined total that barely fills a small parking lot. Hemi-powered convertibles have sold for well over $2 million at major auctions in recent years, while a small-block ‘Cuda convertible in similar condition might bring $65,000 to $100,000. Same body, same year, wildly different world — which is exactly why guessing the engine matters as much as guessing the year.
