Well anything under 100,000 miles is really low mileage. Originally I was considering anything 2000-2007 but recently just started looking at the 06-07 because they are a bit newer and I like the higher HP engine.
But I would be comfortable with anything under 200,000 miles. And I would pay up to $15,000 for one, but there are a ton of people online who think these things are made of gold and won't budge on the price. The kicker is that I have alerts set up on my phone and all I ever see are the same cars getting reposted every week (or more often) on Craigslist. The ones I do find that seem to be in good shape, one-owner, low-miles etc. for a reasonable price all come from the NorthEast and I just refuse to buy a car that spent most of it's life out there unless I can know for sure that it's parked the second snow starts falling.
