Generally, a business is required to deliver on promises made in its advertising, and if it fails to do so, it may be liable for damages. In your case, if the dealership promised you $50 for a test drive, or $200 for a referral fee, and you held up your side of the bargain, you should be entitled to receive those payments. In some instances, a false or misleading advertisement might also arise to the level of a deceptive trade practice, entitling the consumer to increased damages or penalties.
