Hi N.,
I have been there, started out in a Thunderbird and when my second came along decided to get a van. We loved having the open space of the middle seats removed and them sitting in the back row. It was great for changing diapers at the park/store/anywhere, I knew it was clean! Tons of room to put groceries. Relaxing space when traveling if hubby is driving. Easy and comfy to drive. Most are affordable now, though I usually avoid buying brand new. If you need NEW, just about any are good, the Honda Odyssey ranks very high. We have a Pontiac Montana, though we are in a situation needing bigger to fit 5 car seats in now! I love my Montana, won't get rid of it. It is so comfortable and roomier than some others. definitely go for the extended wheel base! At least with a van you have room to grow and you can take "tag-alongs" with you, too! Hope you find something you are happy with!
