...offtopic again...
In addition to very important reasons mentioned above...primary reason for this, in my opinion, is...
BMW AG is afraid to LOOSE "in money making" on this one...Stupid BMW AG just finally realized that fact, was SLOW on this one...
...as someone said, the best way to hurt the rich is to make him poor!...
...NO enthusiasts posts/requests, NO customer complains about new BMWs stupid designs NOTHING changed IGNORANT SELFISH BMW AG mind...until 2004... Ha-Ha-Ha...Many NOTstupid folks stopped buying BMWs and moved to PORSCHES/Audies/Lexuses/Infinities and MBs...
...Finally, looking into it's pockets/bank accounts in 2004! BMW AG started to realize, that they have LESS money, dealers STOPPED ordering new cars at the rate they did just few years ago, most of the new cars ARE STILL sitting on the dealer lots UNSOLD..., but at the same time PORSCHE AG and others are BOOMING?!...BMW AG dramatically changes lease customer acquisition rates for MUCH MORE friendly, despite base price increases NOT working (customers get DISCOUNTS, erasing the later...)...
...back to M5,... in 2004-05 BMW AG M///division engineers visited US and some smart ones+BMW NA sales realized, that if they DO NOT give US FOLKS WHAT WHEY WANT (full power+Manual) they will lose this money game to competition...P400-P500 modes is a good idea BUT ONLY works for EU and specifically German Autobahns, where you can FULLY enjoy true qualities of this new M5. New M5 in contrast to prev. versions IS CALIBRATED PRIMARILY for 100-270 km/h speeds, but NOT 0-100 km/h (as NEEDED in the US with it's speed limited hiwy environment). US needs MORE POWER at slower speed intervals to fight competition...OTHERWISE folks will STOP buying M5s, finally test driving them in REAL US streets environments and realizing, that "the king IS ACTUALLY without clothes..."... Couple of losses on real streets of LA, NYC, Miami, Boston to cheaper Jap. cars, Porsches, MBs and that's IT! Folks will start SELLING them like crazy...
...driving MOST of the time new M5 in P400 mode will KILL M5 as an "ultimate sport sedan idea" on real US streets...
...until new M5 US driver just realizes to go from default P400 mode to P500 and the CAR slowly changes into this mode street EGO competition IS OVER!!!...
...finally realizing above after first few months of owning a car demanding EGO US folks will start dumping M5s for competition...and BMW AG starts loosing money even more...
...MONEY TALKS!!!
...and that's, where PORSCHEs come in, our salvation!...There is no substitute!...
