We drive a Nissan Quest minivan as our family vehicle and we took it in for some warranty items before the warranty ran out. The dealership is nice enough to provide a rental car to use while ours is getting fixed. We really enjoy this part because we get to experience a variety of vehicles and judge how well they fit our family and our needs.
I was excited about getting the Dodge Grand Caravan. Other than the Quest, in my opinion, it's the only other attractive minivan with a large engine I would consider for our family (although I'd consider Toyota Sienna and Honda Odyssey, but they're not attractive).
Mike was excited until he got in the Dodge and began to drive it. He expected more of a 4.0 liter engine. The Quest has a 3.5 liter and exhibits much more response. It handles better overall as well. And, the Dodge was slow. Mike reminded the rest of us of this very fact every time he had to accelerate.
We had to use this loaner vehicle to get to our all-day convention, which was a half an hour away. On Friday morning, Mike pointed out that we would be an hour and a half late by the time we arrived. Seren reminded us why this was: "Daddy, we're going to be so late because this van is SOOOOOOOOO slow!" That wasn't the reason, but it works for me :)
