Awesome list here. Thanks for posting this. I was considering the Acura MSX but after looking at Acura MDX pictures and Infiniti JX pictures, the JX just looks better by far. Presentation is important and the JX is stunning!

Can't beat Infiniti design

Smallest horsepower and torque of the bunch :(

I was also hoping for a bigger gas tank or significantly better gas mileage. :(

Best front legroom :)
Keyless ignition and door operation :) - if the mdx had this i would have bought one already

Dealer said they'd have it starting in april and wanted to take my pre-order. I think i want to see it first.
