Pentagon also reports a good year for the digital side of their business, with unique website visits up by 13% and car and van enquiries via online channels increasing by around 26% over the past12 months.
Pentagon Group chairman Trevor Reeve said: “We set ourselves a big challenge last year when we agreed to add eight new franchises to the group, which included four manufacturers that were brand new to the business”
“This growth means we’ve expanded into new territories with new brands, notably in Lincoln where we now represent seven different franchises.
“Our first dealership opened in Derby in1991, so in what is our 25th year I’m confident that we’re all geared up for a third record breaking year of success”.
This year Pentagon has already opened a new Mitsubishi site on Outer Circe Road in Lincoln.
Pentagon has taken over the franchise from Charles Warner, leasing half of a three-acre site from it after Charles Warner decided the site was too big for its needs and agreed with Mitsubishi Motors in the UK that Pentagon should take its place.
It has also been awarded the Arbarth franchise for Huddersfield.
