Chevrolet of Culver City review
Very nice staff, I felt guided the entire time! Sammy and Rolando helped me out very much, making sure I knew what I was getting myself into and giving me the best options. They helped me buy a car and that feels great!
2021 GMC Sierra 3500 review
Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

Payless Car Sales - ValleyReviews
Payless Car Sales - Valley review
I had a great experience working with Matt Hallman at Payless Car Sales in Wasilla. From the start, he was upfront and honest about their no-haggle pricing, which made the entire process straightforward and stress-free. Matt was friendly, knowledgeable, and easy to work with, he answered all my questions without any pressure. I especially appreciated that there was no push to upsell warranties or add-ons. It was a truly hassle-free car buying experience, and I would definitely recommend Matt to anyone looking for a smooth and honest transaction.

BMW of MurrayReviews
BMW of Murray review
I bought a 2023 Subaru Solterra online from Murray BMW and all went well. Very good communication, once we established a single primary contact. Gerrit was great to work with. Delivery went well- their Transport Coordinator, Matt, was equally on top of things. The only issue I had was a missing Owner's Manual, and they're working on finding me one now. I'd definitely recommend this dealership.

Rick McGills Airport Toyota review
Kevin Frazier is awesome! Not only did he find me the exact car I was looking for - down to the special colors - he keep me informed of it’s travels every step of the way. I got notifications from the time it left the ship from Japan and every jump afterwards until it arrived at the dealership. This has to have been the easiest, and even enjoyable, car purchase I’ve ever experienced. I highly recommend Rick McGill Toyota.
