I'm struggling with this one. I admit to some hearing loss but I have never heard of an auto manufacturer that pauses production at the end of the ending model, manufacture a new generation model, then, change to backfill some ending model orders. Something tells me your car dealer is blowing bubbles here, especially if it has enticed you into leaving a nice £2000 deposit.
In mid August of this past year I ordered a TTS with a similar down payment. It was a nice deal and the dealership just begged for my business. About 45 days into it and not having heard from the dealership, I emailed, then called. When I got no response I called Audi Customer Service. They track orders, too. They didn't have a VIN. They got back to the dealership who then got back to me. Two days later, the dealership's general sales manager confirmed to me that he had been on the phone to Germany and some VP there said that no new 14's were being built for the US market from the beginning of August through January, and indefinitely going forward! The dealership should have known this. I was left with choosing a vehicle already on the ground or in transit. I canceled my order, obtained the return of my initial deposit, drove to an Audi dealer with whom the original dealer refuses to do business, and bought their show room '14 TTS Ibis with 49 mikes on the clock.
I suppose you could play this out and hopefully in June you may have a Mk II, but what if there is a delay in production? You are in Europe. You should have the MKIII this fall. I'd wait for it, if I could not put my hands on the exact car I wanted right now for a very good price.
Remember, you're in the driver's seat.
That's how I see it from my knothole.
