I've experienced excellent care so far from the service department at Stadium Nissan. My service tech, Paul Dixon, took his time with me to fully understand the problems with my 2014 Altima (which had gone unresolved at Royal Oak Nissan.) My car was returned to me on time, and the staff were courteous and professional to boot. I'm very happy with service so far. It's also conveniently located along the LRT, which makes it easy to get to and from work when dealing with maintenance and service.
(I also see there is a commendation for a salesman who used to be at Stadium: Rahat Chawdry. This man sold me my very first car over 20 years ago, and was by far the best salesman I have ever had the pleasure of dealing with. Too bad he is no longer with Nissan...it's really thanks to him that I still drive a Nissan today.)
