Ford
Mustang GT350 20th Anniversary (1984)

Why it matters

The 1984 Mustang GT350 20th Anniversary Edition marked two decades of the Mustang and was essentially an appearance package, sold in the spring of 1984 as the original Mustang had been twenty years earlier. It was a collector car from the start.

Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Ford introduced the edition alongside the SVO in 1984. It was available as a hatchback or convertible, with the 5.0 litre V8 (four-barrel with the five-speed, or throttle-body injected with the automatic) or the turbocharged 2.3 litre four. Ford made 5,260 20th Anniversary GTs; one other source says 5,261, from a 35-day production cycle.
