When most car collectors and enthusiasts ask this question, the minimal criteria to be considered includes the:
A sixth criteria, the transmission type, is often added, however, it isn't necessary in for this discussion.
It's important to note that the term "production" rules out experimental vehicles, pre-production prototypes, as these are typically never sold to the general public.
When we consider the primary five criteria (model year, make, model, body style), two automobiles are tied for one-of-one status, and both were made by Shelby American, Inc.:
Background: For Shelby American, problems immediately plagued the 1967 program and Ford stepped in to take control in October 1966. The convertible and coupe that were ordered in August were still built by Ford and delivered to Shelby American in November 1966. Due to all the launch problems, Ford made the decision to delay the spring-'67 introduction of the convertible and coupe another six months until the 1968 model year. It is hard to grasp why one production car would be built, not as a prototype, however, this is the well-documented reason why just one convertible and one coupe were built.
The coupe (0131) has never been found and is believed to have been "destroyed" because the engine was heavily modified with twin Paxton superchargers and the C-6 automatic transmission was replaced by a 4-speed manual.
The convertible's (0139) original drive-train and Federally mandated safety features remained intact. The car received updated '68 styled fiberglass to be used in marketing photo shoots for the upcoming model year and then was eventually sold to the public through Ford's corporate "B-lot" after Ford shuttered the Shelby American operation in August 1967.

For the rarest "existing" muscle car, please see the answer to "Worlds rarest muscle car?" (sorry, I'd link to the article, however, links are not permitted in answers) When it comes to assembly line built "production" cars, the rarest ever built and still in existence is the 1967 Shelby G.T. 500 Convertible. Though many were planned, only a single example was built at Ford's San Jose, CA assembly plant. Search "1967shelbyconvertible" and there's a site dedicated this this car and all the research and documentation that supports it. Previous answer: The rarrest (sic) existing muscle car is the 1970 Mustang known as the lawman one is in existence owned by Bill Goldberg the professional wrestler. [Edit] Good article on this car in Mustang 360 online.
The "Boss 429" is a type of muscle car. It is said to currently be one of the rarest and most valued car. It is produced by the Ford Mustang car brand company.
The VW Super Beetle is one of the rarest
The graphic associated with this post seems to be more appropriate for "what's the fastest car in the world?"Regarding the "rarest" part: there's a very well-documented answer, and it happens to be an American made muscle/pony car from the late 1960s. See "world's rarest muscle car."You can't count cars still in production, as the could continue to make more, however, it doesn't really matter since "one of one" is as rare as you can get.The crown of rarest production car in the world, which still survives today, belongs to the only 1967 Shelby GT 500 Convertible.Extensive information on this particular car can be found at 1967ShelbyConvertible.comIf this question were rephrased to the be which car is the most expensive sold at auction, there are plenty of auction and private sale statistics that points toward various vintage Ferrari GTOs.Previous answer by Grace Anderson: Bugatti Royale Kellner Coupe this is one of the rarest and expensive care in the world.

Chevelle was probably the Chevrolet Model that best fit the "Muscle car" Description. Corvettes were always first considered a "Sports car" and the Camaro was a "Pony car" a compact version of a Muscle car.
