Looking for advice so that we can start doing some research. So, what vehicles will work to hold 3 car seats? We have a mercury montego and it works with the ones the kids have (both Britax), but, I'm sure I can't fit an infant seat in there too. DH has a ford truck and that will work for all three seats (I think). But, we are likely going to have to get me a new car of some sort.
