Pilling Motor Group has opened a Renault franchise in Milton Keynes this month.
It fills a gap left by the collapse of Camden Group Services earlier this year.
The two-acre dealership, which includes car and van sales and servicing, will be overseen by dealer principal Alex Pilling, grandson of group founder Harry Pilling.
It was formerly a Skoda dealership until the franchise was terminated earlier in the summer.
Alex Pilling said Renault fitted nicely into the group, which already represents Citroen, Mazda, Volvo and Land Rover, and it was a brand that "has always been popular in the Milton Keynes area”.
