Starting in 1966 the GTO went from being a package option to its own model and remained that way until 1971. In 1970 the GTO underwent a major design change that stayed with until 1973 when the front end was changed due to government safety regs concerning bumpers. In 1972, due to declining sales, the GTO reverted back to being an option package on the LeMans and Lemans Sport, costing just $353.88. The most noticable change was in the engine power ratings, which dropped dramatically. This difference reflected the industry.
The car even comes with an 8-track tape player. You can’t get much more than 70’s stock than that. It even works! “Stayin’ alive! Stayin’ alive! wooo, wooo, wooo, wooo, Stayin’ alive!” Sorry, we momentarily forgot that Disco is dead for a reason.
