Where should an "as-is" sale be clearly identified if the dealership is not providing any warranty protection for the customer?

Answer: D — On the purchase contract

In an "as-is" sale, the dealership is not offering any warranty protection for the customer. Therefore, it is important for the dealership to clearly disclose this information to the customer. The most appropriate place to do so would be on the purchase contract, where all the terms and conditions of the sale are documented. Option A, the vehicle's window sticker, is used to display the price and features of the vehicle and is not typically used for legal disclosures. Option B, the vehicle's title, is a legal document that proves ownership and does not typically contain disclosure information. Option C, the salesperson's business card, is used for contact information and does not typically contain information about the sale terms. Overall, the most appropriate and legally binding place to clearly identify an "as-is" sale would be on the purchase contract.
