omg, what a revelation! someone call the press!
as has been said, every manufacturer has a style that is significant, or unique to them.
styling cues that identify a subabishisan as a subabishisan tend to carry through whole model families, if not the whole show room.
and sure the concept cars look great, but they have to build something that is feasible, marketable, and recognisable as a subabishisan. if subabishsan went from being boxy and a aggressive to soft and round like their korean competitors, no ones going to buy it, the fans of the subabishisan will be put off by this sudden change, potential buyers could simply buy the korean competitor and buy their mistress a new kinky outfit, and the hardcore might even switch to another brand.
change in a brand is good, overtime you modify the design of the car, tweak this line a littler higher, make the headlights a little softer, gauge reaction and go from there, make it more appealing to the prospective customers.
blah, its 2 am, probably doesnt make much in the way of sense. meh.
