This would be a deal killer for me on the LE. The whole point of a minivan is to have power doors, so I would really miss the hatch not being powered. Plus it would be hard for my short wife to reach the handle to pull it closed if it wasn't powered.The LE does not have a power tailgate, and does not come with lumbar adjustment for driver. Also doesn't have smart-key access.
Also, if you've ever had a car with smart key (proximity key) it's hard to not have it. So much more convenient.
I got an XLE with Plus package but only because I couldn't find a Platinum. I would have happily paid extra for more features, provided it wasn't a ridiculous mark-up.
