The Behemoth is holding up well after about 17,000 miles. I had a few minor issues in the first months of driving it (a check engine light and some rattles/noises). All of those were taken care of by the dealer and it's been great since.
I figure San Francisco is a good place to durability test a car because the roads here are so bad, terrain is so hilly, and the air is so salty in the Ocean Beach neighbourhood where I live. I notice the car has been getting a bit more rattly when I go over violent bumps (some repairs leave curb-like elevation changes in the street), but I think I'd expect this in any small car that puts up with this kind of abuse. It certainly happened to my 2002 Golf. I have high hopes of getting well into the 6-figure mileage range in this little tank.
