You didn't seriously and honestly tell us that you are concerned about maintenance costs (on a Mazda) and then in the same post ask about high-mileage Range Rovers and Porches did you?
I love those Euro Ute's too but there is a reason that an $80-100k Range goes for 1/4 of it's MSRP in just a few years.
How many miles on the Denali? That seems the most intriguing on that list...
