Here are drawings that were found in some major automotive magazines, illustrating what they believed the new Mustang should/would look like when released.
2005 Mustang GT
MOTOR TREND
These were found in Motor Trend and labeled
as 2004 models. As familiar as those top 2
drawings might seem, I assure you 100%
that they aren't sketches of the 2004 GTO or
even a more fitting 2004 Falcon for that matter.
Although there was those terribly Australian
drawings, there was also some accurate
retro drawings also seen here. HEY LOOK! Its
the grille that's being featured on the new Pony
Package for the V6 Mustang in 2006.
2005 Mustang GT Convertible
Motor Trend
Motor Trend even offered up a convertible version of what they believed could become the new Mustang.
2005 Mustang GT
Road and Track
Road and Track offered us this sketch of what they believed the new Mustang would look like. Nothing on this drawing really carried over to the final model, but the basic form and shape was accurate.
