My experience is based on the service of my car and talking to the service advisor.
I used to have my car serviced at Riverview Nissan, now Larry H Miller { review on them}
They price matched a coupon for a oil change from Larry H Miller Nissan and didn't charge me the $115 diagnostic fee to check out a vibration on my car. Joseph Dianna was pretty great had the tech talk to me and explained what was going on with my car. I have strong opinions on Nissan, Joseph was pretty much a professional and gave me pointers on a car I am thinking of getting.
So that's my story, if I was going to keep my Nissan I'd have Joseph as my service advisor....
