Sherwoods, the family-owned car business, will be turning into a mini-group after expanding into Teeside with the acquisition of a new Vauxhall site.

The former Patrick’s Stockton-on-Tees Vauxhall dealership, was aqcuired for an undisclosed sum, and is expected to lift the family firm’s £55 million annual turnover to £70m.

As well as its headquarters in Chesnut Street, Darlington, Sherwoods runs Chevrolet and used car operations on adjacent sites as well as a Vauxhall dealership in Standard Way, Northallerton.

The Stockton deal secures 43 jobs in sales, aftersales and a bodyshop swelling the company’s workforce to more than 200.

Alasdair MacConachie, owner of Sherwoods, said: “The deal made a lot of sense. We are a particularly healthy dealership and adding Stockton to our family certainly won’t do us any harm.

“I believe the site is yet to fulfil its full potential and I am convinced we have the right management team to move it in the right direction.”

Existing staff at the 2.5-acre site will be retrained and Sherwoods’ management are expecting to boost the workforce in the future. Sherwoods hopes to add the Chevrolet brand to the site too.

The dealership will be run by MacConachie’s son Simon as general manager. He has worked for the family business since leaving school, at the Darlington and Northallerton dealerships.
