It's actually really interesting to see different people's experiences with different Audi dealerships. One of the reasons we've stuck with Audi has been that the service we get from Cambridge Audi is better than anything we've seen anywhere else. But nothing major has gone wrong yet which I guess is the real test. Things that have stood out are (aside from sales, because most dealers at least try at this point) is they've contacted us a coupe of times after we've bought our last two cars to make sure we're happy and take any questions, and when we've taken the car in for service they've replaced small parts under warranty without us having to ask or even flag them. All of this is very different from the service we've seen from Honda and BMW dealerships over the years - but it does sound like it may not be typical of most people's experiences with Audi.
It's our S3 build week next week, so we'll see what happens
