Dealer Testimonials

“The Costco Auto Program has been a lifesaver. Out of all the members we get from Costco, we're selling cars to half of them.”

- F. C. Tempe Dodge Chrysler Jeep

“To be able to connect our dealership with Costco gives us instant credibility. The Costco structure is world class and puts us in touch with customers we would have never seen. The members Costco brings to our dealership are incredibly diverse – it’s always a blessing in today’s very limited buyers’ pool.”

- S.R. (MotoSport Hillsboro)
