I scheduled an oil change and tire rotation along with a complete vehicle inspection and the scheduling process was a breeze. Upon arrival, Carlos Terrazas-Alvarado, my service advisor, greeted me in less than sixty seconds. He then provided a thorough rundown on what to expect during my visit. During my stay I was impressed with the cleanliness of the facility and how professional the staff was. After about an hour, Carlos came to me and walked me through the results of the inspection utilizing great customer service skills coupled with his vast knowledge of the Nissan product. Overall a great experience from start to finish. Thanks Nissan!
Beautiful truck

Shop smarter Not Harder
To me these reviews all sound like everyone wants what they want this is a business that’s selling used cars a tip to help new buyers. You are given a 500 mile or 15 day warranty take the car you buy down to the original dealership or any mechanic have them do a over all inspection if anything is wrong with the car that the warranty covers take it back to the place you bought it from and they are legally obligated to fix it at their expense not yours because it falls under the warranty also make sure you buy GAP INSURANCE AND ANY OTHER EXTENDED WARRANTIES REMEMBER THIS IS YOUR MONEY AND INVESTMENT!!!!! Hope that helps anyone out on here or anyone looking for a car. I AM NOT A LAWYER & THIS INFORMATION IS BASED ON A PERSONAL EXPERIENCE…..
Best truck I ever owned
Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

First I have to say that I am NOT a review leaving
First I have to say that I am NOT a review leaving person, with exception Of Lifted Trucks. In the last 6-7 years the only reviews I have written have been for this store....on with the story... I just purchased my 4th Truck from the Glendale store . This is the 4 truck in 6 six years. The staff does NOT get any better then these folks. From the warm and inviting welcomes to the store to the Superior Management. These are the best people around and I can't thank the enough. I am a customer for life. Thank all of you Sincerely Dan Hubbell
Never had one. Always wanted one and love it.
I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.

I needed a tire repair, my advisor kept me informed on the progress, the waiting room was clean and comfortable and the wait time was short.
Early to tell truck has less than 100 miles
Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

Actually not a bad place to buy a car.
Actually not a bad place to buy a car. I mean, it’s still a car dealership and the usual shenanigans apply, but they will negotiate, and they’re civil and professional. And they give you top for your trade, as I’ve shopped 4 other dealers, they were the best by thousands. Management does a good job too. Frank in particular is a good TO guy. All in all, if they have the car you want, buy from them. You probably won’t do better anywhere else
