There are reports about muscle cars from the 1960s, with some outlets highlighting models that are still affordable, with prices under $30,000. However, the focus of these reports varies, with some discussing the fastest production models, others highlighting underrated or classic cars with high resale value, and one outlet questioning the stability of the muscle car market. The time period of interest also appears to be somewhat broader than just the 1960s, with some outlets referencing the 1970s and 1980s as well.
