I am expecting twins in late April/ early May and need to get a new vehicle like yesterday. Currently I have 3 kids in car seats (ages 2 - 5) so once the babies come it will be 5. I'm having a really hard time finding a vehicle in our price range (about 5K) that will seat the kids with car seats. So my question is if I shell out the money for 3 Radians for my older 3 will they fit 3 across in pretty much any minivan or no? I have had no luck finding any Siennas anywhere near our price range. And it is pretty hard to find a reliable running Suburban for that cheap as well. I can find tons of regular Grand Caravans and Town & Country's but I don't want to buy one and then not be able to fit the car seats in the 3rd row and I hate to buy the carseats before buying a vehicle. I plan on having the 3 big kids in the 3rd row and the babies in the middle row in their infant car seats. Ideas please I'm on a short time line and getting very frustrated.
