Well, it's good she doesn't like VWs, since they are junk. She's just not leaving a lot of realistic options.
There is little to no chance of finding an HX under 60k miles. And you want to avoid the CVT trannies
Nissan Sentra maybe? Here's on that looks pretty clean:
1999 Nissan Sentra
120k miles, manual tranny, $2300. That will save a bunch of up-front costs too. 1999 and earlier had fairly small engines in the base models (1.6L), it jumped up a little in 2000 and the fuel economy dropped.
Toyota Echo or Yaris?
