If you want reliable & cheap to operate, Japanese is the only way to go.
I'd go for a 2WD Toyota pickup, if I were you. You'll probably get the same fuel economy as you would on the Passat, but these things are ultra-reliable and dirt simple.
Another option is a hatchback. You'd be surprised what will fit in a Civic hatchback. These get 35 mpg and are more comfortable than trucks, and just as reliable.
I had an '85 Civic CRX that made 193,000 miles before rusting out too badly. (engine was still a peach) Wore out a ball joint at about 160k, no other mechanical problems.
Now, my '98 Civic CX hatchback has 164,000 on it, and is just starting to rust. No mechanical problems.
Our new '07 Matrix already has 13,000 on it, no problems yet.
