I saw this earlier but didnt have time to reply.

Ok i dont have a Grand Voyager, but i do have a Chrysler Voyager 97 model, we bought second hand 3 and a bit yrs agos.
We have 5 kids in our car, and so far no issues, our voyager doesnt have the gap between the second row, it has two seats together, then the 3 in the back, both rows of chairs fold down and also can be removed from the car altogether.

My hubby loves it, we have been a lil slack on having it serviced due to finances, but in 3 yrs havnt had anything really go wrong with it, the week we got it the radiater went, but they replaced it under warranty.

We usually have two baby seats in the middle row, and a booster seat on the back row, but we only have 1 baby seat now on the middle row so the kids fight ova who is going to sit there, lol

Hubby said its an easy drive and he much prefers to drive the voyager ova his other car that we had at the time.
