Good point - much of the auction data will be from the last few weeks, even months, depending on the car. For example, if you're looking for a Ford Focus, there will be hundreds of sales each month, so tons of recent data, but if it's something less common, say an M5, there might only be a few bits of data over a few months. Point is, like stocks, you need to be able to read and adjust for today, with good knowledge of a local market's ups and downs.
