Foodservice chain Dunkin’ and CarMax, the nation’s largest retailer of used cars, have announced their new partnership that invites people to “do donuts” during their 24-Hour Test Drive. Now through May 16, CarMax customers who participate in the company’s 24-Hour Test Drive will receive a $10 Dunkin’ gift card to keep their daily routine running during their test drive.

“You never truly know if a car is right for you until you’ve taken it through a Dunkin’ drive-thru,” says Melanie Rabino, director, brand engagement at Dunkin’. “Making sure your new vehicle’s cup holders perform perfectly in holding your Dunkin’ Iced Coffee, or other go-to order, is the perfect test.”

Customers who share about their 24-Hour Test Drive experience on Twitter or Instagram by tagging @CarMax, #DoinDonuts, and #24HrTestDrive can participate in a sweepstakes in which 24 people have the chance to win free donuts for a year and a “Doin’ Donuts” signature donut holder.

“At CarMax, we believe the car-buying experience should be as enjoyable as possible while ensuring customers feel confident with their decision, which is why we introduced 24-Hour Test Drives as part of CarMax’s Love Your Car Guarantee,” says Sarah Lane, vice president, marketing at CarMax. “We want customers to experience a day in their life with their new ride, and since America Runs on Dunkin’, we know that includes a trip through the Dunkin’ drive-thru for their favorite order. Collaborating with Dunkin’ on “Doin’ Donuts” makes CarMax’s 24-Hour Test Drive experience that much sweeter.”
