The NEW Body style Mustang will probably go into production in the late fall of 2004 and it will be called a 2005 model.
As for the 2004 model year, from say the fall of 2004 up to and including the end of the summer of 2004, Ford will keep building the current body style Mustang. We will see the BOSS Mustang in the current body style in the end of the summer or fall of 2003 and it will probably be called a 2004 BOSS Mustang. I hope that this information helps you here.
That's not the new Mustang, its a concept. Apparently the production car is significantly different, especially the rear end, and the people I've talked to at Ford say they like the production a lot more than the concept.
Well, I have to agree with the consensus. I think this design is very bad. When I first saw the front end, I thought they had mixed up the Mustang with some sort of truck/convertible crossover vehicle.
If this is just a concept, then I hope the production vehicles is more like the semi-retro concept pics from the magazines. I usually don't like "retro", but I thought the earlier Mustang concept looked pretty sharp...
