I find more and more people use certain terms in their ads to garner views from keyword searches. For example, I also like to look for GTO's around my area. When I search for GTO I get a bunch of other cars pop up as the listing has this as a keyword or included in the ridiculous title. Then if I try to just look for a Judge GTO, essentially the same list appears as people include the word "judge" in their listing. So I am pretty sure Boss, HO, Cobra, Shelby, and SCJ pop up in many ads that have nothing to do with these terms.
In fact, I have done it as well. However, I usually put the disclaimer: "This is not a Boss, Shelby, HO, Cobra, or SCJ" and it has the same effect of populating search lists.
