Now that this threads direction is more car related than audio, I thought I would add my 2-cents.
Being fat, happy and maintaining the status quo, it could be argued that the U.S. big-3 were initially blind-sided by the compact vehicle invasion from the Far East. However, many years passed before their luxury car lines (such as Cadillac) were pummeled by the Infinity, Lexus et al.
Given the length of time it took for this to transition, even the casual observer let alone Cadillac Management -- could foresee the inevitable. The question is, why wasnt G.M./Cadillac capable of improving their products styling, engineering, fit, finish, etc. to be competitive with the anticipated Japanese onslaught?
G.M. has employed educationally, some of the best and brightest engineers in the world, with commensurately hefty salaries. Why couldnt they change? For the same reason why theyre still playing catch-up. Too many old, country club belonging ready-to-retire-to-the-Hamptons Executives. Why would they care to change, and undergo the headaches of doing so? Their current 6 and 7 figure salaries and pensions are guaranteed! Theyre still suffering from too little, too late, as exemplified by the comments responders have made to this thread, and by reviews on the www, in periodicals etc.
Instead of designing and building exciting, attractive, well designed, and fun to own and drive vehicles as their competition, G.M Divisions such as Buick are resurrecting dead engineers (ala the Harley Earl ads), and touting port holes (the ancient Buick symbol). How sad!! The dying off of their buying base is as obvious as was the aforementioned inevitable Luxury car confrontation. Will they be able to equal, or exceed their competition before this happens so far they havent! Moreover, its doubtful they will be able to, before irreversible harm occurs to their once highly revered name plates (Oldsmobile is already dead, which ones next?) not so bad for the million dollar golden parachute owing executives or retirees that have theirs, but too bad for the remainder of the workers, and the U.S Industrial Base in general!
