The new showroom, which is housed on a 1.6-acre site, holds seven cars and features six service bays, as well as an MoT facility. There is also space for up to 80 used cars at the front of the dealership.
Mike Baldry, Crystal Motor Group managing director, says: “Our investment in this facility underlines our commitment to both the brand and our delivery of the highest levels of service to our customers.
“From this new site we can continue to expand the business in line with the undoubted potential that the Nissan product has over the coming months and years.”
Crystal of Grantham was at its old site on Barrowby Road for 33 years but moved due to the continuing growth of the business and the expansion of the Nissan brand.
The investment follows the £1.4m that Crystal Motor Group spent recently opening their new joint Nissan and Renault franchises in Boston.
