I'm not quite following you here. The Pacifica of 15yrs ago had swing doors but the recent version has sliding back doors.
Anywho, we test drove (actually wife drove as this is her choice but I was shotgun) the Odyssey, Pacifica, Grand Caravan Premium and my wife ranked them in that order. Odyssey has more actual room for people but lacks stow'n'go seats and the storage under floor when they're not used. Odyssey looks the best. Wife didn't like the interior design on the Pacifica and felt the Odyssey/Caravan both had equally nice interiors. Odyssey and Pacifica both equal in terms of ride/cornering (Caravan acceptable but noticeably rougher). Wife said Pacifica felt heavier when driving (not underpowered, just heavier).
Honda Dealer: salesman in his 60's, had both Odyssey and Pilot at the front with keys waiting at the scheduled time and knew the features of both well. Took $1300 off the Odyssey right away without being asked just because we know a few of the same people.
Dodge Dealer: salesman arrived to work at the time of Appt 10:30. Pacifica not ready, only had a used model available, huge crack in windshield and a filthy interior. Pulled a Caravan around for us, we got in and it was 15km to empty on gas. We had to wait while he went to gas station. Didn't know features/differences well. Gave employee pricing and said they wouldn't budge any more.
Pricepoint the Pacifica is $6000 more than a similar spec Odyssey to get what we want of cruise and heated front seats and Airplay (nav from phone onto screen as adding nav to vehicle adds a lot).
Caravan has no Airplay so you have to add Nav which adds a whole bunch of things to get it which puts it same price as Odyssey but with that adds power doors and a couple other nice things.
We're going to go with the Odyssey as it was both my favourite and more importantly my wifes. Either the LX or EX depending where the final numbers come back at.
