Engine light came on, rough shifting, Adam in Service
Engine light came on, rough shifting, Adam in Service dept fit my truck in for diagnostics within a week. Tech found bad coil, replaced and repaired, also suggested new wires and battery was needing to be replace really low crank, all work completed and again on the road after 310,000 miles. I have had only good experiences with the service department staff and techs. Sometimes it cost some money but its a machine and if you take care or it, it will last.

Ryan did a GREAT job as did everyone else.
Purchased a 20yr old Nissan from Ryan, he and the team there gave me as much information and the condition of the vehicle as was possible based on the age and of course based on the age the car does have its issues which I had expected, but Ryan did a great job of working things out and as I arrived really late he and the necessary people to finish a deal were there and ready to help. I picked the car up the next morning with a full tank of gas ready for my 300 mile trip home. They gave me a great deal on the vehicle, far below what they were asking all said and done out the door.
There are 4 matching cars close to your year range.
