Professional from the start and they were not as much
Professional from the start and they were not as much pressure as so many other dealers.
One of the best looking suv's on the road. Highly
Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

Cyia was extremely helpful and pleasant.
Cyia was extremely helpful and pleasant. I ended up buying elsewhere at a dealership that was closer to me. It is not a reflection of anything the dealer did or didn't do. I spoke with Cyia and thanked him. He was very accepting and cordial.
Amazing SUV
I’ve had an amazing experience with terrain Denali. I had it for 3 years and it was one of the best cars ever. Everything worked perfectly no issued at all! Loved it

I just purchased a BMW i3 from Emich and it was great experience, they answered all questions and sent an i packet with photo's and records I asked for walk through video's driving video's Haley the salesperson. answered e-mail very fast. I had the car delivered to me and all went very smooth. Only thing better is if they were in KS.
Grea4 mileage and comfort
Bought it used. The shifter on the dash takes getting used to. But after a month I no longer grab for the shifter arm. Have been happy with comfort. Driving. Gas mileage. Would recommend it.

These guys are the best.
These guys are the best. They made the buying process very easy. Thanks for everything Gilberto Rivera and the owner Julio!!!
Try this SUV before you buy another!
Frank Kent in COrsicana, TX gave me a great deal on my trade-in and on my new Terrain! I was intending to by a VW Taos that morning but when I saw the Terrain AT4 and drove it a little, GAME OVER ! I came home in the stylish and comfortable AT4.

I generally do not do reviews, but I feel I must express
I generally do not do reviews, but I feel I must express my experience with Valley Nissan in Longmont, Colorado. I live in Boulder and have been considering a new Nissan Leaf, after contacting several dealerships, I have to say that Valley Nissan was by far the BEST experience I've ever had with a car dealership. From my initial contact with Blake the Internet Director, outstanding communication, he respected my preference in the way I wanted to communicate, answered my questions quickly and directly. Once I arrived at the dealership I was greeted by both Blake and my sales consultant Leon, who had all paperwork ready to go for a quicker transition. Leon went over the car with me , answered all of my questions and was very knowledgeable; (this was very appreciated as this is my first electric car). This outstanding customer service continued with the Finance Manager Nate, he came out and introduced himself to me, explained the rest of the process and when I would be with him to finalize all paperwork. The thing that impressed me with Nate was, he did not try and sell me a bunch of products/coverage, he presented me with what he would recommend based on how I was purchasing my car-so refreshing! What a great team at Valley Nissan, I would recommend anyone looking for a vehicle to reach out to these guys! So worth the short trip from Boulder, this review seems longer than my time in purchasing my new car. Thanks Again to All, Weston Boulder, CO.
