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 - 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.

Key Chevrolet GMC Of Newport review
These guys were absolutely awesome we've been looking for 3 months for the right truck that had certain things on it. My salesman was Alex an was awesome. I asked multiple questions an if he was unsure he got right back to me. We live 3.5 hrs away an did want to waste out time. The sales manager an credit guy was also awesome we drove away with a really nice truck they made it a great experience. Yes I would travel again to buy from these guys. Well worth the time.

Karma DFW Plano review
Karma DFW was very responsive. I was interested in a 928 GTS but it turned out to have an automatic transmission. The write up had stated it was a manual transmission but the pics included showed it was an automatic transmission. Karma DFW verified it was an automatic. I was looking for a manual transmission.
