There are cheap cars with low mileage, expensive cars with low mileage, expensive cars with high mileage, and cheap cars with high mileage, and everything in between. Unless the cheapest car also has the lowest mileage, and the most expensive car also has the highest mileage, there is no "best" or "worst" in this classification.
There is only a tradeoff between inputs, the two primary ones shown here are mileage and price, with age overlaid by color/dot size.
2D data requires visualization and human interpretation - There is no algorithm in place here. A list only works on 1 dimensional data (and can be parsed trivially with a simple sort algorithm). 3D and higher dimension data requires more complex visualization and more effort to parse.
A visualization allowing the user to make good decisions based on several inputs is a great place to find 'the money'.
