X3 weaknesses
 There is definite hesitation when attempting quick acceleration.  The gps is horrendous!  Neither my husband nor myself have figured out how to enter addresses.  It just shouldn't be this difficult.  His aftermarket gps works like a dream.  Not only is it easy to imput data, but also warns of traffic slow downs and alternative routes.  The stereo is mediocre.  The controls are mediocre.
