id certainly say that the service is completely random from one dealership to the next.
I live in cov and work in warwick, i would never go back to the cov dealership, the service imo is rubbish, and to be fair coming from quite a few audi's i was used to good service, the nissan garage in warwick felt like i was back at audi, exactly what you want.
It is a shame that you almost didnt end up in a zed! Made the right choice in the end though!
