I love the styling of the new Quest. I think it makes it the best looking minivan on the market. The non-removable seats aren't a big deal to me, I think in 5 years I've removed the seats from our Ody just one time. Considering the endless parade of troubles with our '03 Odyssey I will look very seriously at the Quest when it hits the market. Honestly, this was our 1st Honda and I can't say it's impressed me on the reliability front...my Saab is generally more reliable.
Love it. the inside looks nicely built...high quality. I do own another Infiniti and it's going very well. So maybe when it's time to look for another minivan, the Nissan Quest will be a major consideration.
I hate the boxy back end. But the bigger problem is no 8 passenger seating. I don't know how the fold down mechanisms work in the new Quest, but its hard to imagine anything better than Honda's (the new Sienna's is nice that it is power in the XLE, but it takes much longer.)
