We've been kind of looking for a new family SUV. Today we have a trusty Honda Pilot AWD - a great SUV, dependable, reliable and reasonably comfy. It's getting up there in miles and age and we're thinking of a replacement. Certainly a newer Pilot is an option too, but I like those sleek GL450s and GL550s from MB.

I wonder about their reliability and longevity. Looking for at 2010 or newer, about 60-80K miles, probably leaning towards GL450 at this point - less money and the difference is probably negligible to us anyway.

Here are some candidates on local CL:

https://denver.craigslist.org/cto/d/mercedes-benz-gl450/6397542325.html

Is this going to be an expensive ride to maintain past 100K miles?
