Wilson and Co unveiled new facilities at its Bolton showroom following a £1 million refurbishment of the dealership.
A 50% increase in floor space will allow the Vauxhall retailer to display 14 new cars at the upgraded site on Manchester Road which has been subject to six months of renovation works.
Vauxhall Motors chairman and managing director Rory Harvey officially open the new showroom, the Bolton News reported.
Staff will benefit from new office and furniture and take advantage of new side-rooms, allowing customers to discuss their purchases in private.
For customers, there is now a larger, more comfortable waiting area, including a coffee machine and dedicated children's area complete with toys at the facility, which was purchased by Wilson and Co back in 2004.
Wilson and Co's group took over the dealership in 2004
Wilson and Co has five dealerships at Bolton, Chorley, Scunthorpe, Grimsby and Boston.
In 2014 the group achieved a turnover of £61,148,000 according to figures gleaned from AMi.
