We've been running 'bangernomics' cars as part of gathering some cash for the move. Each one had been no more than £750, run it for a few months, then sold for what we paid, and purchase something with longer MOT. You do of course need to watch what you're buying, but so far, so good. Our car budget when we arrive should be 6k aud which is slightly better, but not massive. I'm expecting to purchase something for that which will be fine until we get work sorted out and then it will become the second car. If you're not too fussy in terms if what you drive, its amazing what you can pick up.
