Walser Buick GMC BloomingtonReviews
Walser Buick GMC Bloomington review
I brought my truck in for oil change, tire rotation and to resolve a warning light issue regarding the Tire Monitoring System. I left my truck overnight for a next day appointment and received a text by 7:30 am stating that the oil change and tire rotation had begun and that the tire sensor battery was dead causing the warning light to engage. I was given an estimate to replace the battery and was asked if I wanted to proceed with the repair. Since I have a lifetime warranty, I asked the service advisor to contact the warranty company to learn if the repair was covered. The advisor did so and luckily it was covered. The communication was very timely and accurate and the work on the truck was excellent. I've been to numerous dealerships for vehicle service and Walser Buick GMC Bloomington is by far the best.

Very responsive and helpful! Although I didn’t end up buying from TVS, I would not hesitate to in the future. If they made me happy as someone who didn’t buy from them, I know being an actual paying customer would be amazing!

Dishman Dodge RAM Chrysler Jeep review
Can't say enough good things about my experience buying my truck from them. It was a no pressure experience. Very nice people from the salesman to the finance guy. Both went the extra mile to make sure I felt good about my purchase. Very upfront with no surprises.

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.

Van Horn Chevrolet of Plymouth review
I dealt with Van Horn on an SUV for about a week. The vibe was so good that I ended up driving 900 miles on a Tuesday to make a purchase with them. I buy a lot of vehicles and I have never seen people stand behind their vehicles with such customer care and loyalty. They will earn your businesses.Very, very impressed and happy with their first class service and amazing warranty. I highly recommend Van Horn Chevrolet and their sales team.

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.

Payless Car Sales - AnchorageReviews
Payless Car Sales - Anchorage review
I recently purchased a white Range Rover from Payless Cars, and I couldn’t be happier with the experience. From start to finish, everything was smooth, straightforward, and genuinely enjoyable. Quinn was outstanding to work with; professional, knowledgeable, and never pushy. He made sure I got an amazing deal and took the time to answer all my questions without making me feel rushed. The entire process was fast, efficient, and stress-free, which is rare when buying a car. If you’re looking for a dealership that actually takes care of its customers, I highly recommend Payless Cars, and definitely ask for Quinn. They made this one of the easiest and best car-buying experiences I’ve had.
