Unfortunately it’s out of their control when the car will be delivered. Once they place an order it’s up to the manufacturer to decide when they will manufacture your car. Then there is the delivery time to reach your dealer. They probably only ship the cars after so many has been built etc etc.
Your best bet is to ring around Renault dealers to see if they have one in stock or if they have one being manufactured for their stock. You might be limited to what colours they have.
