4 cars between the two of us. I've got my Honda Civic 2002, Jeep Cherokee Laredo 2008, Z4 3.0si 2008 and my wife's Acadia.
The Civic is the DD for me. I use the Jeep in winter when there's too much snow on the ground or I expect there to be too much snow on the ground.
Z4 is my weekend car. Sometimes I drive it to work.
Acadia is my wife's ride. Perfect for hauling the kids around if you don't want a minivan.
