Hello S.! Allow me to completely disagree with the rest and share with you my vehicular excitement - the new Dodge Charger! Before you freak out on me, it has PLENTY of space for (up to) 2 kids. If you're planning on more....go ahead and go with the minivan moms. :D It has TONS of trunk space, it's luxurious inside, and if you have the money, it can run up to $40k, but the V6s with moderate equipping will probably run more like $28-30k. Not to sound like a dang Dodge dealership here, but MAN I love my car so much, and if you buy a brand new one, Dodge is running it's $2.99/gal gas for 3 years and you get a lifetime powertrain warranty and a 1 year subscription to Sirius radio and, if you get one, Sirius backseat TV (Disney, Nickelodean (sp??), and Cartoon Network).
I've had my new Charger for a little over 2 months, I have one daughter, but I can easily see two toddler-sized carseats in the back of this car. The interior is huge, as is the trunk. They can come with backseat TVs and headsets that ONLY work in the backseat (they don't even work in the front passenger seat) if you plan on any long trips (it can also play DVDs).
Maybe the minivans others have mentioned come with these things (especially the Dodge Caravan probably), but I just wanted to open the door a little to these awesome cars that many women discount because they're "muscle cars" not "family cars". The new ones are MADE to be Family Muscle Cars. Check it out! We got ours from Hoover on Trolley Rd in Summerville, but Hendrick on Savannah Hwy has some too, I'm pretty sure. Best of luck in your car quest!! :D
