The measure allows a “cooling off period” whereby the buyers of used vehicles could return a vehicle to the car dealer within three days of purchase, defines a “certified” used vehicle to mean only a vehicle that has met specified standards, including that it has not sustained damage which “substantially impairs” its use, value, or safety, and requires that car dealers disclose certain information to car buyers. Specifically, the measure requires that the car dealers’ disclosures include the buyer’s credit score and the monthly cost to the buyer of after-market items.
