In response to my new M3, my wife has decided she wants out of her minivan (a gigantic Nissan Quest referred to in our house as the mini-barge) and into a regular, reasonably sized, car. While this is a reasonable request, the catch is she wants the minivan to remain as the third car. This means I need to give up my X3. Unfortunately, after 135k miles I have become quite attached to my X3. The debate has centered on which is more important, the ability to transport seven people at once or the ability to be mobile in any weather condition. We have three garage bays at our disposal and the idea of keeping a fourth car outside during a New England winter is not an attractive option. So, I was interested in thoughts regarding this debate. Pros, cons and, really my true motive here, new and creative reasons to argue in favor of keeping the X3.
