I'm surprised to see some of the bad reviews about this dealership as well as the brand. I've had 2 S4s and just recently bought my 3rd (CPO since I love the manual transmission on the S4s) back at the end of Jan 2020. My experience dealing with the Audi Kingston sales, service and parts staff since moving here to Kingston from Toronto have always been great. They are pleasant, friendly and cheerful.
I dealt with Michael Rowcliffe when I purchased the 2015 S4 they had. The vehicle looked awesome and I even purchased their new ceramic paint protection as I intend to keep this car for a very long time. I've had the car for about a month now and up until yesterday had no issues. I picked up the car with approx. 62K on it and after careful inspection on delivery I noticed a couple of 2 small dings on the car. No biggie, it was a used vehicle and had a clean Carfax. I also noticed that the bottom left front of the grill had a small crack (not visible unless you really get on the ground and look at it). Again, no biggie since you can't really see it. Yesterday after work, I started my S4 to find that the clutch all of sudden failed :( I purchased the extended warranty and it's now being sorted out. I'm hoping that this is just a fluke thing and nothing else happens.
I can honestly say, I'm somewhat jaded when it comes to the brand since this is my 4th vehicle and have been fortunate to not have any issues. Will keep posting as necessary.
