The expanding family-run business opened the north east London site on Fore Street to keep up with customer demand.
Westdrive Edmonton consists of a 10 car showroom and a full service and finance facility. The showroom has eight sales executives, eight technicians and there is space for 85 used cars outside.
Steve Bullimore, dealer principal for the Edmonton and Westdrive's Romford site, said: "We are delighted to announce the opening of our new Edmonton Showroom. The opening will provide a further expansion that is not only expected to strengthen the dealership stable, but the Kia brand as a whole. "The new showroom will allow Westdrive to bring the fantastic Kia model range to a larger audience. Westdrive is hugely proud to be the largest UK dealer of a growing brand that is continually developing and innovating in such a way."
