Sliders values are averaged together to provide the best possible match for any given combination of indicators. To this effect, the slider positions are for comparison purposes only and not all vehicles shown may reflect all criteria which has been selected. If a larger number of sliders is used, a broader range of values must be averaged and the accuracy of the results will diminish slightly. If fewer sliders are used, the accuracy increases. The optimal number of sliders is 3 to 6.
