1968 Plymouth Road Runner in B5 Blue & 426 Hemi Engine

A trunk hinge that still creaks and a spare tire that’s apparently never touched pavement — small details that tell Mopar collectors everything about how untouched this 1968 Plymouth Road Runner really is. Owner Jeff Fleming has kept the QQ1-blue, 426 Hemi car since 2013, correcting a common mix-up with the following year’s B5 Blue paint code along the way. Commenters call the color-and-engine combination the best Plymouth ever built.

A car that’s never been touched tends to tell on itself in small ways — a creak in the trunk hinge that’s never been oiled, a spare tire that’s never once touched pavement in over fifty years. This 1968 Plymouth Road Runner has both, and neither is a flaw — together they’re proof of something most muscle cars from this era can’t claim. Its owner has kept it since 2013, one piece of a Mopar collection serious enough that fellow enthusiasts call parking it beside a ’68 Charger, a ’70 Road Runner, and a modern SRT Challenger something close to a religious experience. Under the hood sits an engine and color combination commenters routinely call the best Plymouth ever built. So what makes a fifty-year-old car this untouched?

Filmed in a Driveway in Northwest Indiana

Lou Costabile filmed this walkaround for his “My Car Story” series on February 19, 2017, in a driveway in Northwest Indiana, working through the car in the same conversational format that defines the series — no scripted narration, just Costabile and the owner circling the car while the camera catches details a static photo never would. The trunk creak that viewers latched onto in the comments happens on camera when the lid is lifted to reveal the spare tire, a small unscripted moment that ended up meaning more to Mopar enthusiasts than any spec recitation could have. Costabile lets those moments breathe rather than cutting around them, which is part of why his channel has built a following among collectors who care as much about a car’s condition story as its horsepower numbers. The Hemi fires up partway through, and the idle alone is enough to explain why commenters flagged the sound as one of the video’s highlights.

Plymouth’s Cheap Muscle Car That Changed Everything

The Road Runner nameplate exists because Plymouth made a deliberate bet in 1968: strip a muscle car down to essentials, price it under $3,000, and sell raw performance without the trim-level markup buyers were paying elsewhere. Plymouth licensed the Road Runner name and likeness directly from Warner Bros., down to a horn that mimicked the cartoon character’s “beep-beep,” a novelty that helped the car sell over 44,000 units in its debut year alone — numbers that stunned Plymouth’s own sales projections. That approach flipped the muscle car formula on its head; rather than loading up a mid-size coupe with options, Plymouth deleted them, keeping the car light and putting the money into the engine bay instead. The strategy worked well enough that Pontiac’s GTO and Chevrolet’s Chevelle SS both faced a genuine budget-performance competitor for the first time, and the segment reshuffled almost overnight around Plymouth’s no-frills formula.

1968: The Year the Road Runner Arrived

This car represents the nameplate’s very first model year, before Plymouth added the GTX-adjacent trim options and softer edges that came with later Road Runners. The 1968 body rode on Chrysler’s B-platform, shared with the Belvedere and Satellite, but Plymouth’s marketing leaned entirely into the no-nonsense angle — bench seat standard, rubber floor mats standard, and a base 383-cubic-inch V8 that buyers could upgrade straight to the 426 Hemi for a few hundred dollars more. Few did; Hemi-optioned Road Runners were a small fraction of total 1968 production because the engine’s price premium and insurance surcharge scared off exactly the budget-minded buyer the car was built for. That rarity is precisely why a documented, unmolested 1968 Hemi car carries so much weight with collectors today — it represents buyers who wanted the strip-level Road Runner concept and the top engine option simultaneously, a combination Plymouth itself expected relatively few people to choose.

QQ1 Paint and the Hemi Underneath

The video’s title calls this car’s color B5 Blue, but that’s a labeling slip worth correcting: the B5 paint code didn’t exist until Plymouth introduced it for the 1969 model year. This 1968 car actually wears QQ1, a similar-looking blue from Chrysler’s 1968 palette that predates B5 by a full model year, and mixing the two up is a common mistake even among longtime Mopar fans given how close the shades appear in person. Underneath that QQ1 paint sits the 426 Hemi, Chrysler’s 426-cubic-inch, hemispherical-head V8 rated at 425 horsepower from the factory, backed in most 1968 applications by a four-speed manual or TorqueFlite automatic. Commenters on the video specifically call out this QQ1-and-Hemi pairing as the best color-and-engine combination Plymouth ever offered on the Road Runner, a claim that holds up given how few 1968 buyers actually checked both boxes on the order form.

Jeff Fleming’s Collection, Five Years and Counting

Owner Jeff Fleming has held onto this Road Runner since 2013, and the car is one entry in a broader collection that marks him as a serious, longtime Mopar collector rather than a single-car enthusiast. That context matters on camera — Fleming talks about the car with the kind of granular knowledge that comes from owning several muscle cars simultaneously and understanding exactly how this one compares, down to noting details like the trunk hinge creak and the never-used spare almost as a point of pride rather than an oversight to fix. Collectors who own multiple period-correct cars tend to develop a sharper eye for originality than single-car owners, since they’re constantly comparing build details across their own garage, and Fleming’s comfort walking Costabile through the car’s unrestored quirks reflects exactly that kind of experience. It’s the difference between someone reciting a spec sheet and someone who actually knows what “original” is supposed to look and sound like.

Why a Creaky Trunk Is a Selling Point

In the collector world, small imperfections like a stiff trunk hinge or a spare tire that’s never touched a road are read as evidence, not flaws — they’re signs a car has never been disassembled, repainted, or refreshed to the point where those original textures got erased. A fully restored Road Runner might look flawless in photos, but a car that still creaks exactly the way it did rolling off the Chrysler assembly line in 1968 tells a documented, continuous story that restoration can’t replicate. That’s exactly why Hemi Road Runners with this kind of untouched provenance command such a premium over comparable cars that have been through a repaint or an engine swap; originality has become the rarer commodity even among cars that were already rare on the day they were built. Commenters specifically flagged the unused spare as proof this Road Runner has spent most of its fifty-plus years being preserved rather than driven hard, which is a distinct — and more valuable — kind of survivor story.

GTO, Chevelle SS, and the Budget Muscle Wars

The Road Runner’s closest 1968 rivals were Pontiac’s GTO and Chevrolet’s Chevelle SS 396, both of which offered comparable big-block performance but leaned harder into trim, options, and a higher base price than Plymouth’s stripped-down approach. The GTO carried more standard equipment and a stronger brand cachet from its mid-’60s muscle car pioneer status, while the Chevelle SS split buyers between a 325-horsepower base engine and the more serious 375-horsepower L78 396, giving Chevrolet a wider spread of price points than Plymouth’s single-minded Road Runner formula offered. None of Plymouth’s direct competitors, though, matched the Road Runner’s specific pitch of a genuinely bare-bones car with a genuinely serious optional engine — GM’s equivalents dressed performance up with more comfort and more cost. That gap is exactly what let the Road Runner outsell projections in its debut year and forced GM’s marketing teams to respond with their own lower-trim performance packages within a couple of model years.

Decoding a Real 1968 Hemi Road Runner

Because Hemi Road Runners are among the most cloned muscle cars in the hobby, verifying an original means matching the VIN’s engine code against Chrysler’s fender tag, confirming the block casting numbers and date codes line up with 1968 production, and checking that the car’s build sheet — if it survives — lists the Hemi option rather than a later engine swap. QQ1-painted cars add another layer of scrutiny since the color’s brief window of use makes it easier to spot repaints that don’t match period-correct formulations. Buyers should also expect four-speed Hemi cars to carry a documented Dana 60 rear end, a heavier-duty unit Chrysler paired with the 426 to handle the engine’s torque, since a mismatched rear axle is a common tell on a car that’s had drivetrain work done. A well-documented example like this one — original paint, unrestored trunk hardware, verifiable Hemi codes — sits at the very top of what 1968 Road Runner collectors are willing to pay for.

Mopar Heaven, One Driveway at a Time

One commenter summed up what this video captures better than any spec sheet could: seeing this 1968 Road Runner parked alongside a ’68 Charger, a ’70 Road Runner, and a modern SRT Challenger felt like “Mopar heaven,” a reminder that these cars were never meant to be appreciated in isolation. Plymouth kept the Road Runner nameplate alive all the way through 1980 precisely because the original 1968 formula — strip it down, keep it fast, keep it affordable — proved durable enough to echo all the way into the SRT era. A car like this one, still wearing its original QQ1 paint and still creaking the way it did the day it left the factory, isn’t just a survivor; it’s a direct link between the budget-muscle experiment Plymouth ran in 1968 and the six-figure performance cars carrying the same spirit today. Jeff Fleming’s decision to keep it unrestored rather than “improve” it is exactly why it still has that story to tell.
