Carl Long started racing at Orange County Speedway in Rougemont, North Carolina and South Boston Speedway in 1983. After winning track championships at both facilities, the Roxboro, NC native advanced up the motorsports ladder, qualifying for his first Cup race in 2000. Carl made 174 starts across the three national series of NASCAR, including 26 in the premier series. He worked as a driver, crew chief, spotter, mechanic, competition director: any position needed to get his car to the track. In 2014, Carl co-founded Motorsports Business Management LLC, and he continues to lead and grow the Statesville, NC organization today.

The NASCAR Cup Series branch of this operation has been racing since 2017 with more than 125 premier series starts. In 2025 and beyond, the Cup team will compete as Garage 66 and plans to enter 20 or more race weekends with the No. 66 Ford Mustang Dark Horse this season.

The NASCAR Xfinity Series team out of the same shop competes as MBM Motorsports. MBM has amassed more than 630 Xfinity Series starts and provided opportunities to numerous drivers and crew members. MBM achieved its best finish in organization history in 2022 at Daytona (2nd place) and has now recorded seven Top 10s and 25 Top 15s.
