They seem to be stable for the past month or two. The late model prices (the ones Nick is asking about) are down significantly from 6-12 months ago, with many asking prices on the '97 in the $54-57K range, vs low sixties a year ago. Model years later than '97 are difficult to determine because there are so few of them, and owners put them up for sale with false hopes of getting close to what they paid for them.
Since Steven raised the topic of the early models, I don't think the prices of the '91-92 have changed much - maybe a grand or two (like he says), at most. It's difficult to tell, because many of the older cars being represented as clean are not. The older the car, the bigger the differences in condition, and the more that comes into play in determining price.
I haven't noticed any evidence of prices rising. There may be a seasonal rise in another couple of months, with the approach of spring and warmer weather.
