Perhaps Ford will use typical after market ideas on the 2012
I just bought a 2011 V6, candy red Mustang with the Pony Pkg; it is quite a car. I, also, kept a highly modded 1995 6 speed Camaro Z28 with 400HP. So i, now, have a daily driver and a hot rod. I like individualizing my car a bit.
Many of the changes in this 2011 Mustang came from after market engineers. I traded a 2006 Mustang, Pony Pkg in and there is no comparison between the two ponies. The 2011 handles like a Ferreri and stops like one too. Except for the exterior mirror adjustment there is no similarity. BlueTooth, 305 stock HP, 6 speed, Handling improvements and Sync are so advanced that I feel foolish having spent $19,000 souping up the Camaro.
Because of size differences and Ford connections the after market will make some creative improvements. Alan Mullali, Ford's CEO, is from Boeing and demands cutting edge engineering. He made the engineers and designers at Ford push the edges of the envelope. His staff understands enthusists and demands performance. The best concepts from Asia, the after market, aerospace, information technology, Silicon Valley and European auto manufacturing are baked into the 2011 Mustang.
Continuous improvement means he'll put more good ideas, styling and technology into the 2012 models and that may mean SEMA suppliers will reduce offerings. I won't be foolish again and spend so much modding when I know next year's Ford will be better from jump street. So I am happy with America and my new Ford. If the next year's car is a quantum leap forward like the 2011 was, I'll trade up if it makes financial sense to do so.
