As the 356 was continually refined and perfected through the 1950s, engineers felt they were reaching fundamental limits of the design and began planning the next leap forward for Porsche. Released in 1964, the 911 was conceived as a larger, more powerful, more comfortable evolution of the 356. As with the 356 before it, the 911 was (and is) defined by continual performance innovations punctuated with the occasional styling update: non-experts will have trouble casually distinguishing a 1960s 911 from a 1970s or 1980s car. Newer generations of the 911 continue the legacy of quality, reliability, and that signature Porsche responsiveness that connects driver to road.
Collectors entering the 911 market face a vast range of selections, as Porsche designers made countless significant revisions to the model over the past 50 years, not to mention a river of small-batch variants with niche tunings and numerous options, often with different specs for various global markets.
