i posted this in the other thread, but it seems to be more appropriate here:
perhaps an excel sheet (or whatever) with the categories for the cars listed...then, the weighting is described as given in the article...for example, if there are 10 categories, perhaps the default setting is each category is worth 10 points, but the weighting is variable, so you could put specific categories higher, like value, driving dynamics, whatever...you could make them worth more and others worth less...so perhaps a car that scores lower in "style" won't get hurt as much...if such a chart/spreadsheet were available to the readers, it would allow them to formulate their own versions (i suppose they could simply make their own if they knew how)...and each reader/customer could either leave everything even or boost categories most important to them (fuel economy, space, etc).
