I'm pretty sure I've seen them for over $100,000.00. The upside is depreciation is horrendous, so if it's what you really want you can into one almost reasonably. They're a long way from where they started, some Cadillac bits on a Tahoe. I'd wager 90+% of them are leased. I have a buddy who looked at them, they quoted a $1,354.00 lease payment and called it "very reasonable".
We have a Durango instead of a full size GM SUV for two reasons, cost and my perception of GM quality. Right now I think they're where Chrysler was in the late '70's. We replaced a Ramcharger with the Durango, the only thing I really miss is the spacious width of the Ramcharger, the Durango is too darned narrow. Other than that every other category is an overwhelming win for the D, well, except fuel economy, very similar numbers.
