[Oh Captain My Captain]

So we just had our third child this past month. My wife is now suggesting that my 2010 Z4 may need to be changed. We presently also have a MDX and E-Class. The main issue is that the nanny now drives the MDX and in the winter, this puts us in a bit of a pinch. Last winter I rented a Jeep for three months and that is not an appealing option. There is no room for a fourth car. Before buying the Z4, I had pre-ordered an X6 5.0 (you can probably find my old posts about the debate). Looks like I am back in the same predicament.

Thoughts? I'm content to rent again but there have been issues with me not being able to help transport the kids around b/c "my" car doesn't have the room.

As I write this I realized that the price difference between the vehicles would take me about 8 winters of renting.
