My opinion....4 children....best car for you...

We have one. We bought a Honda Odyssey...gorgeous car...but when we fouund out prg with #4 the Odyssey just didnt work . We did heaps of research, and DH found the chrysler the best for us. THe older two can walk down the back of the car to their seats (we have 3 x Maxi Riders in the car, and 1 x rear facing SNS.....) , buckle themselves in. DD#3 gets put in on passenger side, DS gets put in behind driver. AND there is still one more seat in between DD#1 and DD#2.....
In my opinion....you will never, ever have enough room in a car with 4 children.....but if the space you do have works, and no one is uncomfortable, then in my opinion, it works. We have a strider and todd. seat in the boot. It can fit a nappy bag too....im guilty of dumping a lot of stuff on the front passenger seat...easy access and all. IF we ALL went on a holiday, we would have to buy a pod or something to fit on the roof....but TBH....i m not going to not buy a car coz it wont do us for our yearly holidays...im more interested in day to day stuff...and the chrysler works for us... As long as each child had easy access to their seat, mummy and daddy could do their seatbelts up without too much pain, then it worked for us.
We bought a 2004 model this time last year for $15k....air con and a few other things were not working, we spent about $5k all up on repairs.
Truly hon, you will not look back. Even yesterday whilst in the car with all the kids, DH said to me ' i would recommend this car to anyone with 4 kids'....so true.

Its an AMerican car - so yes, parts are expensive, but its sturdy, its heavy yes, but it feels firm....(if that makes sense....). But if you get a half decent one, and look after it, get regular check ups, then its all part of having a car really isnt it ???? We got ours with only 60,000kms....

ETA: Chrysler windows in the back of the car dont open either.....the very very back ones push out electronically from the front control panel, but sometimes we find it can get stuffy in the back...so we virtually always have the aircon on low....

TBH....i think its a no brainer for you......and FWIW.....theres 2 other mums at our school....one has 4 kids, the other looks after a few, and they both have chryslers.....GL.....
