I mean, it always depends. I've always driven smallish, reliable Japanese cars, a couple Mazdas, my wife had a Corolla, we've got the Honda, so that's kind of my frame of reference. If I'm looking at those manufacturers and spending ~$9,000 on a used car today, I'm looking at things like '03 Civics, saw an '04 Nissan Sentra listed, an '03 Camry. These are good cars that still have some life to them, but still... those are cars with seven or eight years and 80k or 90k miles on them. Even the reliable ones start needing things like brake jobs and new clutches and new exhausts systems at some point.
I figure, with the Civic, I've had it since it was brand-new. We'll probably end up owning it for ten years, I don't see us trading it in until the_Wife is screaming and crying to get a minivan.
If instead of the new Civic, I'd bought an $8k or $9k car back in 2005, I'd probably have driven it into the ground by now and I'd be be buying ANOTHER $8k or $9k car. So, I figure I spent $16k on a car that I'll end up driving for 10 years. instead of spending $8k or $9k *twice over that same period (and having twice as many maintenance issues).
But, it all depends on the particulars of what you're looking at. I'm also perfectly happy driving the same car for ten years, which I know not everyone wants to do (despite my love of Top Gear, I'm not really that much of a car guy).
And, I know the quality of some of the American cars has gone up recently, so maybe you can get a decent Ford that's a little newer for than same $8k or $9k.
