The dealership, which is expected to open in summer 2020, follows the takeover of the Rodenbourg and Étoile Garage businesses.
It will house the Citroën and DS dealerships of La Cloche d'Or and Peugeot Strassen (Peugeot and Kia) in a 10,000m2 plot offering 20,000m2 of space over four levels.
Starting mid-2020, some 130 employees are expected to work at Car Avenue. The brand began in 1936 when André Bailly opened the first Peugeot dealership of the group in Metz. Today the group has a presence on 80 sites in France, Luxembourg and Belgium.
