Drove that same truck Monday; while impressive, not sure it's worth the nearly $59k admission. To put another way, that's nearly what a 3/4 Mega LH 6.7 retails for, and about $7k more than one with a 6.4. Not sure the value is there, but, ****, was it impressive! Just because you asked; yes, the air suspensions definetly makes a difference in every aspect (Cadillac DTS ride, CTS handling). The truck has Mercedes interior luxury and finishes and Volvo seat comfort. While the diesel is, indeed, impressive, I'm reserving further judgement until more long term data comes in. What I'm most worried about is how long sysems will last; my $3,000 turbo lasted 85,000 ($1,300 and counting for the rebuild, plus a huge amount of wasted time and cash outlay for special tools needed to get it out). Also concerned about all the emissions garbage they now require; main reason the turbo failed to begin with, and I've been deleted over 40,000. If there is a lifetime-type warranty available that covers all it's a no-brainer; however, I don't want to be towing 15 years down the road and have all that crap go out, as it would probably costs multiple thousands of dollars and a lot of down-time to fix (Italian diesels are not what I would call reliable; Lombardini, anyone?) Knowing me, I'll roll the dice, anyway, and find religion again (keep praying it doesn't brake). I specify longevity because I want to get what I want and have it paid off before retirement age; after that there may be no more chances to go this big again, so it has to last.
Otherwise, with a few options deletions and color changes, that is exactly what I want. And, oh, the smell of that leather!!!
As for the stupid shift buttons, didn't give them a first look this time and actually forgot about them most of the test.
