BMW has its mojo back
 In Jan 2017 I replaced my bmw435i xdrive  with the 440ixdrive with track package and manual trans; while the cars are very similar, the440 is big improvement; for a slight increase in price, more items are standard; seats better, interior nicer; entertainment system better ;although the is no longer hardwire controller for the i pod;but the main improvement is in PERFORMANCE;the new six is stronger smoother with better gas mileage; handling improved with quicker response more accurate steering ; more powerful brakes ;firmer but comfortable ride and that was with winter tires; the above mentioned is even better with the stock non runflat  Michelain pilot  summer tires;while the 435 was extremely  competant, this car has a stronger driver connection and is fun to drive
