Which of the following is considered a deceptive practice under the Colorado Consumer Protection Act?

The Colorado Consumer Protection Act is designed to prevent deceptive trade practices and protect consumers from unfair tactics used by businesses. Among the options provided, all of them can be classified as deceptive practices under this act.

Providing misleading representations about vehicle features can lead consumers to make uninformed purchasing decisions. If a dealership advertises a vehicle as having certain features that it does not possess, it constitutes a form of deception.

Bait and switch advertising is another tactic where a dealer advertises a vehicle at a low price to attract customers but then tries to persuade them to purchase a different, often more expensive vehicle. This type of practice is clearly intended to mislead consumers and is therefore considered deceptive.

While providing detailed vehicle history is essential and beneficial for transparency, misleading representations directly contradict the principle of fair trading and could result in a consumer being misled about the actual condition or value of a vehicle.

Since each of these practices can mislead consumers in different ways, all of them fall under the umbrella of deceptive practices as defined by the Colorado Consumer Protection Act, making 'all of the above' the correct answer.
