Pentagon Group will be adding Chrysler, Jeep and Dodge to its portfolio before the end of January.
All three brands will be integrated alongside its existing Vauxhall dealership in Greengate near Manchester and they are also bringing the same franchises to Barnsley.
Chrysler, Dodge and Jeep will be situated in a re-furbished building at Barugh Green in Barnsley on a site where Pentagon also represent Chevrolet.
Pentagon is continuing to expand the amount of brands it represents following its appointment as the new Subaru dealer in Ashbourne, Derbyshire.
Trevor Reeve, group managing director, said: “We are of course very pleased to be able to bring these new franchises to the group and this now brings the total number of franchise sales outlets represented by Pentagon to 23.
“We jumped at the opportunity to diversify our manufacturer representation and these new additions to the Pentagon Group fit well with our long-term strategy of building a successful, multi-franchise motor retail group.
“In 2010 we will continue to evaluate further growth opportunities, and I am confident that in February we will be in a position to announce that Pentagon will be appointed by another two manufacturers in key locations, both of which will be new to us.”
Pentagon now represents Vauxhall in 11 locations, Chevrolet in six locations, both Saab and Chrysler, Dodge and Jeep in two locations plus Peugeot and Subaru in one location each.
