I've driven the long-term Infiniti JX35 before, and was reminded this week that the luxury crossover uses what's essentially the same instrument cluster as the long-term 2013 Nissan Altima I drive as a Motor Trend long-termer -- from the tachometer/speedometer to the trip computer screen and the advanced, tilted-back info screen. The Infiniti gets a little purple ring and special silver trim around the edges of the tachometer and speedometer, but I don't know if that's really enough to distinguish it from the Altima and Pathfinder.
Riding in the third-row seat to a local restaurant, my mom found there was decent rear-seat space, and my other half remembers the Ford Flex's third row as being less spacious than the one in the Infiniti.
The JX35 does have a couple interesting styling details. I like the JX35's big wheels and overall shape, and from the driver's seat, its swirly leather seat pattern. Though the crossover's 3.5-liter V-6 is fine for most driving situations, I wouldn't mind a little more low-end torque. It will be interesting to see how JX35/QX60 sales will be affected by the introduction of the 2014 Acura MDX.
