2006 Mustang, a success, but is it enough? The Mustang is certainly a home run for Ford, exceeding projected sales by almost 50%, they've stopped taking orders on 2005 models and told dealers to start taking orders for 2006. They can't keep GT's on the lot and even the V-6 model doesn't linger for long. http://www.usatoday.com/money/autos/2005-06-27-mustang-usat_x.htm

With new special models in the pipeline, like the new Pony package for the V-6 and rumored Mach 1(spotted by AutoProphet; http://theautoprophet.blogspot.com ) and California Specials (BlueOvalNews) as well as the much anticipated Shelby GT 500 by SVT, it's likely that Mustang will sell very well for the next few years.

It's rumored that Chrysler may release a 2 door version of their new Charger called the challenger, hoping to sell as many as 60,000 a year, chipping away at Mustang sales. And let's not forget GM, there are rumors flying (although it may not happen) of a new Camaro/Firebird.
Ford definitely has a headstart on these models, but with sales under 200,000 per year, the Mustang may not be enough.

Ford really needs the new Fusion/Milan/Zephyr models to take off and fast.
