Yes, it’s absolutely true:

Mark Wahlberg owns a Chevrolet dealership in Columbus, Ohio. It’s not a weekend publicity stunt. It’s for real. And along with opening a future Wahlburgers in Central Ohio–plus looking into becoming part-owner of Columbus Crew SC–he has proudly been promoting his new car dealership on local news and popular talk shows.

Exhibit E. 

As a Columbus, Ohio resident, I’m waiting to see Mark Wahlberg Chevy commercials, possibly including the one seen above.
