Car dealer group Vospers is to add the Seat franchise to its portfolio for the first time.
The family-owned AM100 motor retailer is investing £750,000 into extending its multi-franchised site at Marsh Mills, Plymouth, to accommodate the VW Group brand.
The development is expected to be finished in March. At the same time, Vospers is updating its Mazda showroom at Marsh Mills to the latest corporate identity, and investing further in its Ford dealership in Exeter and a site at Truro.
Chairman Peter Vosper and his son, managing director Nick Vosper, told the Plymouth Herald the group's investment comes after the strongest car market in a decade.
In 2014 the car dealer group sold 8,553 new cars, 4,540 used cars and 4,058 new and used vans.
