The key to success in this business is being very disciplined in buying. Limit your car buying to popular models that you can turn over quickly, models that you have a strong understanding of current local pricing on, cars that you can buy at a significant discount to the price you believe you can fairly sell them for, and cars that are highly unlikely to need major work.
Even large companies and organizations that offer products and services that are widely used and mass marketed often use niche marketing techniques. Most major car companies, for example, now offer energy-efficient hybrid models of their automobiles that appeal to niche segments of the population—environmentalists and urban drivers with long commutes. They hone in on that smaller segment of their market with high visibility on city highways and in the stores, magazines, and online sites frequented by especially “green” consumers.

With few exceptions, such as American Idol, the Super Bowl and the Olympics, it is not common for a substantial audience to watch a program at once. Still, networks do target particular demographics. Lifetime targets women and MTV targets youth. Sports channels, for example, STAR Sports, ESPN, STAR Cricket, and Fox Sports, target the niche market of sports enthusiasts.
