RICHMOND, Va. -

A new CarMax program invites people to “do donuts” during their 24-Hour Test Drive experience.

Only these donuts are the delicious kind, with frosting and sprinkles.

Dunkin’— the all-day stop for coffee and baked goods — is participating in a program in which CarMax customers who participate in the 24-Hour Test Drive through May 16 will receive a $10 Dunkin’ gift card.

CarMax’s 24-Hour Test Drive offering is a part of the company’s signature experience — the Love Your Car Guarantee — allowing customers to experience a day in their life with a new vehicle prior to purchase. That program also includes a 30-day money back guarantee, giving customers 30 days to love their car or return it for a full refund up to 1,500 miles.

Sarah Lane, CarMax vice president of marketing, said CarMax introduced the donut program as part of its Love Your Car Guarantee because the company believes customers deserve an enjoyable car-buying experience while also feeling confident with their decision.

“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,” Lane said in a news release. “Collaborating with Dunkin’ on “Doin’ Donuts” makes CarMax’s 24-Hour Test Drive experience that much sweeter.”

Customers who take a 24-Hour Test Drive at participating CarMax locations will also receive a checklist of ideas to help them get the most out of their 24 hours. Those include taking their dog for a drive and packing the trunk with their favorite cargo to ensure it fits.

And, of course, those ideas include a visit to a drive-thru to make sure the cup holder can fit their Dunkin’ Iced Coffee.

Customers can also discuss their 24-Hour Test Drive experience on Twitter or Instagram by tagging @CarMax, #DoinDonuts, and #24HrTestDrive. The companies are hosting a sweepstakes in which 24 people can win free donuts for a year and a “Doin’ Donuts” signature donut holder. More information is available on official rules, eligibility and participating locations.

“You never truly know if a car is right for you until you’ve taken it through a Dunkin’ drive-thru,” said 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.”

Actress, author, and podcast host Busy Philipps is also part of the program. She is demonstrating via Instagram what she recommends doing during a test drive.

And of course, she can’t start the day without Dunkin’.

“Everyone wants to be in control of their car-buying decisions,” Philipps said. “CarMax not only made my experience fun, but they also provided ease and confidence with a 24-Hour Test Drive fueled by Dunkin’. Having the car for a full day gave me the ability to see and learn every feature and how it seamlessly fit into my busy schedule.”
