What information must dealerships provide to customers upon request about previous owners?

The correct answer is the names and addresses of previous owners because Wisconsin law requires that dealerships disclose the history of a vehicle, including its previous ownership, to potential buyers upon request. This information is crucial for consumers as it provides insight into the vehicle's past, including how many times it may have been sold and the amount of care it has received from prior owners. It helps buyers make informed decisions regarding the vehicle's reliability and potential issues that could arise from its history.

While documented history of vehicle repairs, the original purchase price, and service records can provide valuable information about the vehicle's condition and maintenance, they are not mandated by law to be disclosed upon request. This focus on the previous owners ensures transparency and trust in the vehicle sales process, fostering a better purchasing experience for customers.
