We had 2 kids in a Saturn 4 dr, about 4 months after having our second we were given a 4 dr blazer. It worked out okay, either the Saturn or the Blazer seemed large enough for running around town. The Blazer had a little more vertical space in the cargo area, but I as I recall the stroller didn't really fit as well as in the trunk of my Saturn, the distance between the wheel wells was too narrow so almost everything had to be put in at an angle which meant that the stroller alone took up all the cargo space, the blazer did have a trailer hitch that I used a couple times to tow a u-haul trailer. When we had our third we bought a mini-van and it was an improvement, the sliding doors make getting in and out a lot easier but there still isn't much cargo space unless you remove one of the rear seats and the MPG is less than good. I'd consider the build quality of any mini-van to be below average compared to the compact and mid size market today. Having owned a 4 dr econobox, mid size SUV and mini-van with 2 children, I'd suggest sticking with the sedan for now. Unless you plan on getting in and out of the car a lot, there isn't really a huge advantage to owning something larger than a 4 door sedan. Once the kids get a little older you might need something with a bit more room in the back seat, but for now just look for car seats that fit in your car and you'll be fine.
