Will not start, louisy Customer Service
 The car only has 300 miles and the battery died three times!Dealer (Motorweks) claoims everything is according to specs and battery runs down because of all electronics and that I must drive the car 3-4 times a week or use a trickle charger at all times!!! Contacted BMW customer service and they send me a standard staementthat they bild "The Ultimate Machine" and that I must contact the dealer.I asked if I must take a very long extension cord for the charger when I travel for more that afew days but no one thinks it is funny!Would seem to me that electronics can be interlcked with the start switch so the only run when car is started???
