The 2004 model year

Overview

The send-off. 2004 was the last year of the fourth generation before the all-new retro S197 arrived for 2005, and the Mustang's 40th Anniversary. The Mach 1 and supercharged Terminator Cobra continued at full strength; a 40th Anniversary package added unique colors, stripes, and badging. Fourth-generation production ended in May 2004. (Horsepower figures are SAE net.)

Year over year

What changed

  • Final year of the fourth generation — the retro S197 replaced it for 2005.
  • 40th Anniversary package: special Crimson Red (plus white/black), stripes, badging, and trim (Standard and GT).
  • Mid-year the 3.8 L V6 was replaced by a 3.9 L version of the same Essex engine (identical output).
  • Mach 1 and supercharged Cobra continued unchanged.

Worth knowing

Notable

  • "Last of the line" appeal — final fourth-gen year and the Mustang's 40th Anniversary.
  • The supercharged Terminator Cobra and the Mach 1 are the collectible picks; the 40th Anniversary Crimson Red cars are a recognizable send-off trim.
  • Fourth-generation production ended in May 2004.

Living with it

Reliability & ownership notes

  • Same as 2003 for the performance cars: very strong Terminator bottom end, supercharger/intercooler upkeep, DOHC Mach 1 and Cobra IRS as buying checkpoints — buy on documentation.
  • Final New Edge body and modular-V8 notes apply (convertible seals, front-end rust on weathered cars).
