They seem determined to go down the same
road as Chevrolet, that is, the introduction of cars
with no real market potential, relying on buyer
"loyalty" while offering them no real reason TO
be loyal.
The Mustang as a car and the F150 pick-up are the
only vehicles that are likely to inspire any brand
loyalty.  
But look what's coming. The 500.  Why would they introduce
something like this?  A formless mish-mash of Taurus
and (I think) Crown Victoria.  It isn't 1986 anymore Ford,
you can't sell something that looks and performs like
this and expect people to really buy it.
On top of this, Ford has other problems.  Their service is
terrible, as evidenced from myriad responses by Ford owners,
they show a real disdain for pre-existing customers. The paint quality
on their cars falls below that of Hyundai, way below.  Fit and finish
on their cars is also poor compared with the Japanese.
The only hope for Ford if they can't seem to improve on these kinds
of points is to do what Chrysler has done;  Keep a few (two) key
vehicles, and start making interesting new ones.  Only
variety will keep people's minds of the quality issues Ford cannot
seem to solve.
