I picked the above "reason" because it's the worst feature of an otherwise perfect vehicle. The durability of the interior is quite frankly an embarassment. I've lost the buttons for max for the heater, up for the driver side temerature, and the top button for the airflow direction .... don't ask me where they went, they just disappeared! I've broken the drivers side cup holder (and come on ... how pathetic are those cup holders!), and once it breaks, it no longer clicks back into the closed position so now I have a half a cup holder sticking out. One other grievance relating to interior durability ... the plastic footrest (left foot) down below the hood lever also fell apart. The plastic just broke away in full 2002 BMW 5-Series review
