The building has been wrapped up with a 95 x 42 meter red ribbon and has a seven meter bow on the M4 facing side, greeting commuters into Cardiff from the east.
Ashley Cleverly, marketing and communications manager at Cardiff Audi, said: "We wanted to do something different to the usual sending of Christmas cards this year. The showroom is really impressive so we thought we would take advantage of its size and location and do something that not only our customers will enjoy, but also our neighbours on the business park and the people that get stuck in traffic on the M4."
The Christmas themed dealership was opened launched with a party featuring festive snacks and mulled wine.
Cardiff Audi also made a donation to local charity, TY Hafan which cares for children with life limiting illnesses. Some of the children and their families attended the event and were treated to traditional Christmas carols by children from the St David’s Church in Wales School.
