Normally, Warriors guard Steph is the Curry family member who is featured in advertisements, but Mavericks guard Seth Curry, Steph’s brother, is the headliner of a CarMax partnership.

And it appears Seth had a lot of fun in the process.

Seth Curry, whom the Mavericks signed as a free agent this summer, recently surprised Dallas-based fan Theo Bray with a “test drive delivery.”

“You didn’t know it was going to be me [delivering]," Curry tells Bray during the test drive, in a Chevrolet Tahoe. “You caught me on my side job.”

He’s kidding, of course. The Mavericks well-compensated Curry with a four-year, $32 million contract this summer.

Curry’s surprise visit and test drive are part of a CarMax partnership with Curry and the NBA Players Association. The video that was shot that day is part of a fall advertising campaign that launches Wednesday to highlight CarMax’s new personalized car-buying experience.

“It was so exciting to meet Seth,” Bray said in a news release. “To get a chance to meet one of your favorite players that you’ve admired from afar for so many years and then just getting a chance to see him as a flesh and blood human being— as a man, as a father. It was just amazing.”

Bray added that he had “no idea whatsoever” Curry would show up on his doorstep.

“It’s always fun to get up close and personal with a real Mavs fan and just see how much they appreciate what we do on a daily basis,” recently married and new father Curry said. “But it was also nice just to learn about Theo’s life and get some advice from him about his family of four kids now.”
