I had a great experience at Crest Nissan!
I had a great experience at Crest Nissan! From start to finish, everything went smoothly and in a timely manner. The staff was professional, friendly, and attentive, making sure all my questions were answered and that I felt comfortable throughout the entire process. It's clear they value customer satisfaction and work efficiently to get things done right. I highly recommend Crest Nissan to anyone looking for a hassle-free and positive car buying experience.

I’m looking and have been for a while. I have found most car sells men don’t care what they say to sell a car. I was pleasantly impressed with a young man by the name of Luke Fox when showed me the cars and all that entails. When I make my final I hope I can buy it from Mr Fox. Thank you Luke

Walked in here because one of our fleet vehicles was in
Walked in here because one of our fleet vehicles was in need of some costly repairs. Ended up trading the vehicle in for a new one. Think I?ve found the new dealership I?m going to buy all our vehicles from here on out. From the moment I was greeted by Mike Sui, salesman, I felt welcome and at home. The process was painless and relatively quick. We ended up being able to find a one stop shop that would would wrap our vehicles as well. And cheaper than the previous prices we were quoted, all in. Two thumbs up.

Fast service and very professional
I bought a year old BMW. The price was better than I found at other dealerships. They were prepared to go as slow as I wanted and answer all my questions, but that's not what I wanted. I wanted fast! So after a quick test drive went in and signed the paperwork, while they washed it for me. They let me leave my old car there and drive my new car home. There was a headlight malfunction and they said it was completely covered under warranty. However, because it was a software issue, Carmax said I needed to take it to BMW, but that Carmax would cover any costs. They were true to their word!
