The Top Garage award has been received by co-owners and founders of Cedar Garage, Kevin Pearce and Matthew Copp at the Top Technician/Top Garage Awards, held at the weekend in Northamptonshire.
The final was extremely tight, with four garages vying for the title.
Cedar Garage is based in Tarring Road in Worthing, and opened a second site in the town in Littlehampton Road earlier this year.
The business received an extensive prize package worth several thousand pounds, including items from sponsors Pico Technology, Pro-Align, Ring Automotive and Snap-on, as well as training from competition supporters Auto iQ.
There was also a £1,000 cash prize from Aftermarket magazine.
Commenting on their achievement, Kevin said: “We are ecstatic to have won Top Garage.
“The whole team has worked their socks off, and it is great that their commitment has been recognised in this way.”
Matthew added: “We are so happy to have won.
“Everyone in the team has the same attitude as us- they want to be the best, and this is a fantastic way to show the work that goes into the business.”
