first of all, if you're saying that valentine1 is to radar detectors as what lexus is to cars...i would have to disagree.
alternative - n. - something which can be chosen instead (Merriam-Webster)
so. here we have a choice, as consumers. we can either choose to buy the valentine1 for its various benefits OR we can choose to buy something else other than the valentine1. ITS A CHOICE. surely there are consequences to our choices(ex. performance, style, cost), but it's up to the consumer to choose which alternative is best suited for their individual situation.
i think some of us have incorrect definitions of alternative; along the lines of something synonymous to equal to or same as.
also...i very much doubt that hyundai owners say they own equivalents to lexus.
also...it appears some of us need to learn how to use quotation marks jk
