Ordered the 450 in February and took delivery in April, convenience 2 and heavily optioned but skipped the off-road stuff, automatic cruise, panoramic roof, and lane-assist.
Would have ordered the diesel but dealers steered me clear given biodiesel content in Illinois - no complaints with the V-8; sounds great.
This is not, however, a car that cries to be driven fast - big (which is why I bought it), heavy vehicle.
Awesome for interstate cruising or tooling around town.
Very quiet; smooth ride, although I hate the numb electronic steering.
Great styling inside and out.
Command system works fine for me, extremely comfortable, lots of convenience features.
As good as advertised.
Park assist is fantastic; if you parallel park much, you should try it - saves your rims from scraping the curve, and the big vehicle has some blind spots (wish I would have got the blind-spot detection). Love the vented, massaging seats.
Auto headlight package is very convenient and works well - bright, safe, looks great.
I love the lighted running boards and interior ambient lighting at night.
Commanding view of road; you just feel good driving this.
Need more speeds than on/off for rear wiper - as it gets a lot of water on rear window.
Steering really is numb, as all of the press writes about.
Wish second row seats adjusted.
These are mostly minor items (steering aside).
