Breakdown of the 25 Best Muscle Cars to Own (Part 2 – Chrysler)

The Chrysler 300L closed out one of Detroit’s most overlooked performance lineages in 1965, a 413 cubic inch V8 rated at 360 horsepower, wrapped in a plush, comfort-focused body that arguably invented the muscle car formula before the term existed. With only 2,845 built, including 440 convertibles, this entry breaks down what made the letter series’ final chapter both rare and surprisingly affordable. Read on to find out why it might be the segment’s best value.

By the time Chrysler reached the end of the alphabet with its “letter series” cars, the company had already spent a decade building some of the most overlooked performance sedans in Detroit history. The 300L, produced only in 1965, was the last of that line, and one of the least talked about. It shares none of the fame of a GTO or a Road Runner, yet it was built with a formula that arguably invented the muscle car concept years before either of those names existed.

How the Letter Series Began

Chrysler’s 300 letter series launched in 1955 with the C-300, followed by the 300B in 1956 and the 300C in 1957, then continued forward through the alphabet until the run ended with the 300L in 1965. Each successive letter represented a genuine mechanical update rather than a simple trim refresh, which is part of why the series is considered by some historians to represent the true beginning of the muscle car era, predating the more famous mid-1960s intermediates.

What Was Under the Hood

The 300L came equipped with a four-barrel carburetor feeding a 413 cubic inch, 6.6 liter, V8 rated at 360 brake horsepower at 4,800 rpm, with 470 lb-ft of torque arriving at 3,200 rpm. Those output figures held steady whether the car was ordered with the three-speed automatic or the four-speed manual transmission, a level of consistency that was unusual for a full-size performance car of the period.

Built for Comfort as Much as Speed

Unlike some of its more stripped-down muscle car contemporaries, the 300L was engineered with genuine creature comfort in mind. The interior was tasteful but plush, loaded with the available technology of its day, while still delivering the performance Chrysler’s letter series was known for. That combination of comfort and capability set the tone for what Chrysler buyers would come to expect from its performance flagship.

A Genuinely Rare Production Run

Only 2,845 examples of the 300L left the factory in 1965, and just 440 of those were convertibles. That scarcity puts it well below the production numbers of most muscle cars from the same period, yet the 300L rarely commands the same attention, or the same price, as more famous, higher-volume cars from the era.

Why It Might Be the Best Value in the Series

Because the 300L shares its engineering and build quality with pricier Chrysler models like the Fury and the Imperial, restoration costs run comparable to those cars, but the 300L’s purchase price has historically undercut them. That gap makes it arguably the most cost-effective entry point into the entire letter series.

What They Cost New, and What That Tells Buyers Today

A 1965 300L hardtop originally listed for around $4,090, with the convertible adding roughly $460 to that price. Those figures illustrate just how much of a premium buyers paid for performance and comfort in a full-size package, a premium that echoes in the car’s continued rarity today.

Mechanically Sound, and Built to Last

Chrysler engineered the letter series to be mechanically robust, which is part of why surviving 300L examples remain sound and drivable decades later. That durability, combined with genuine scarcity, ensures the 300L will likely always carry solid resale value among collectors who know the series’ history.

How the 300L Compares to Its Chrysler Siblings

Where the Fury leaned toward flash and the Imperial leaned toward pure luxury, the 300L split the difference, offering genuine performance credentials without sacrificing the comfort buyers expected from a top-tier Chrysler product. That balance is part of why the letter series built such a loyal following among buyers who wanted a fast car that did not feel like a stripped-down muscle car underneath.

Why the Letter Series Ended in 1965

Chrysler retired the numbered letter series after the 300L as the broader market shifted toward the mid-size performance cars that would come to define the muscle car era through the rest of the decade. The 300 nameplate continued afterward, but never again with the same numbered, year-over-year mechanical progression that had defined the original series from 1955 through 1965.

What to Look for When Buying a 300L Today

Given the low production numbers, buyers researching a 300L purchase should prioritize matching-numbers drivetrains and factory build sheets over cosmetic condition alone, since a numbers-matching example, even one needing cosmetic work, will consistently command stronger interest than a nicely refinished car with an unverifiable drivetrain history.

The 300 Nameplate’s Legacy Today

Though the numbered letter series ended with the 300L, the Chrysler 300 name has been revived multiple times since, most recently as a modern rear-wheel-drive sedan that borrowed styling cues and a performance-oriented positioning from its 1960s ancestor. That continuity has helped keep interest in the original letter series alive among younger collectors discovering the lineage for the first time, rather than the cars fading into obscurity as many lower-production models from the era have.

Restoration Considerations Specific to the 300L

Because the 300L shares its unibody platform and many mechanical components with other full-size 1965 Chrysler products, parts sourcing is more manageable than the low production number alone would suggest. Reproduction trim and interior pieces are more limited than for the mass-produced Fury, however, which means originality-focused restorers often need to budget extra time for sourcing correct trim rather than assuming everything will be available off the shelf.

What Makes the 300L a Smart Long-Term Hold

Collectors who specialize in full-size 1960s performance cars point to the 300L combination of documented low production, genuine period performance credentials, and a purchase price that has historically lagged behind comparable Chrysler models as a formula that tends to reward patient ownership. Unlike more speculative segments of the collector market, where prices can swing sharply based on trends, the letter series has built its reputation slowly over decades, appealing to buyers who value documented history over hype. That steady, unglamorous appreciation is exactly the kind of profile long-term collectors look for, even if it means the 300L will likely never command the same headline auction results as a GTO or a Hemi Road Runner. For a buyer building a collection around genuine rarity rather than name recognition, the 300L remains one of the more compelling cases in the entire Chrysler lineup.

How the Letter Series Set the Template for Later Chrysler Flagships

Beyond the nameplate itself, the letter series established a template Chrysler would return to repeatedly in later decades: pair genuine performance credentials with a level of comfort and equipment that a stripped-down muscle car buyer would never expect, then price the result as a flagship rather than a budget performance option. That formula echoes directly in later Chrysler performance sedans that emphasized comfort alongside capability rather than choosing one at the expense of the other, a positioning strategy that traces its roots back to exactly the balance the 300 letter series struck between 1955 and 1965. Collectors who study the lineage closely tend to view the 300L less as an endpoint and more as a bridge, the car that closed one chapter of Chrysler performance while quietly setting the philosophical template for how the brand would approach the category again in later years.

The Case for Driving a 300L Rather Than Trailering It

Unlike some lower-production collectibles that owners tend to preserve behind glass, a well-sorted 300L rewards genuine use on the road, since the entire point of the letter series was building a car that could be driven hard and comfortably across long distances rather than simply displayed. The four-speed cars in particular reward an owner willing to work the gearbox rather than let the automatic do everything, and the combination of period-correct torque and a genuinely comfortable cabin makes the 300L one of the more usable full-size performance classics from its decade for anyone who actually wants to put miles on a collector car rather than trailer it between shows.
