Dacia is next on my list (currently have a 17yo ford that's beginning to get too expensive). several of my colleagues have them.
Having just filled a Diesel tank that went from €60 (last fill c600km ago) to €80 (today), 1.4l engine, my bicyle is looking even more low cost.
I drive a Dacia with LPG. The car is ok, but of course don't await it to be comfortable. It vibrates more, is loud especially at high speed. And there are many little "quirks" like: To let down the window at the back seats, the buttons to do so are in the middle console instead at the front door.
For my needs thats enough. The trick is to never buy a better car, so you don't get used to the more comfortable features. :)
*will still get a Dacia for necessity, though.
