I as looking at a Grand Caravan GT as well I could have saved a fair amount on the cost of the vehicle.
What really sold me on a Pacifica was all the updated features that the GC just doesn't have.
My favorite is Enter-N-Go just walk up to the door and grab the door handle and the door unlocks. Then just put your foot on the break and press the start button. Keys never leave my pocket.
Then there is Apple CarPlay and Android Auto, I like that the interior feels wider I'm not sure it actually is or not.
So here's the funny thing with all that. My 2014 Town & Country is a Limited, later years they split it into limited / limited platinum, and the 2014 limited = limited platinum. It has the walk up and touch the handle to unlock the doors, blind spot warning sensors as well as normal backup sensors, rear cross traffic sensors, push button start, DVD + Blu-Ray players with separate screens for 2nd and 3rd row, sunroof, tow package, 115V outlets in the back along with HDMI / composite inputs and usb ports, and power \remote 3rd row, doors, and trunk, plus upgraded 9 speaker sound system with a subwoofer. I think most folks have no idea that they had all of that 7 years ago. This is why I said the GT was a downgrade for me.
So the only thing I'm missing is Apple Carplay. I definitely like the way the Pacifica drives better, and it's a quieter vehicle. The only things I really care about though are the rear cross traffic alerts, blind spot monitoring, the tow package. The problem is that GTs with the sensors are rare, and the Pac has super low ground clearance. Tow kits can be added to either, but I'd have some reservations about putting a tow kit on a long wheelbase minivan with only 5.1" of ground clearance.
I'm really looking at the AWD Pac now. From what I've read they have 0.8" extra clearance except at one point on the exhaust where it has to clear the driveshaft to the rear diff. That may be a good compromise.
