When targeting customers of the consumer population at market a product, what type of segmentation information would be most ?

Suppose you are selling automotive detailing products. Is your target “anyone with money to pay for your product?” Or are you focusing your efforts on a tightly defined market segment of people with an identified need for what you are selling? “Anyone with money” is such a broad audience that it’s difficult to make any impact at all with your marketing efforts or convince very many people that they need your product.  If you narrow and carefully define your target market, though, your efforts will be more fruitful because they’re focused on people with a preexisting need or interest in what you offer.
