I came out of my one-owner 2008 QX-56 to pick up a Yukon Denali. The Yuke is 4" longer and 1.5" wider, and weight is 100 lbs less than the Infiniti, so you could argue they are the same size. I got the LZ0, and though the characteristics are different compared to the QX-56 V8, the HP is about the same while the torque is 100 lbs higher with the LZ0.
Because I wanted the LZ0, the dealer was unable to let me specify anything other than color if I wanted something PDQ (I had been trying to order since December). That said, no regrets on the size. The Yuke fits into all of my garage spaces just like the Infiniti. Mileage so far has been 24.2 with only 500 miles on it. Even though I had done upgrades to the Infiniti that made it drive and ride better than new, the Yuke blows me away with its ride and handling. Sweet for an SUV. I thought I would want to downgrade to 22" wheels, but these 24" rims are fine.
Here are my regrets:
- no bench seat for the middle row; wasn't an option
- middle row captain's seats won't fold; also not an option
- hate the collision avoidance systems; too much trouble to disable; the blind spot visual warning is fine
- ASS, though I quickly installed an Autostop Eliminator, which works as advertised
- not a fan of Supercruise, but couldn't avoid that option and I don't use it
- would have eliminated the rear entertainment if I could; screens block view for rear passengers
Had I known the middle row would not fold, MAYBE I would have considered the XL.
