We were looking to replace my wife’s vehicle and went to
We were looking to replace my wife’s vehicle and went to a couple of different places looking for a vehicle. Schrier was the only dealership we went to that actually addressed her about a vehicle (it was for her after all). While they did not have a vehicle on the lot that met our needs, they spent several days looking for one and communicating with us about options. After a few days they found something that they could get from out of state that looked good on paper, but would take several days to get on-site. Our sales person (Stewart), did a great job of communicating with us and providing timely updates. The vehicle was delivered to them, but there was a discrepancy on what they had been told (and told us) and what was delivered. We were able to discuss and in the end made a deal that we believe was fair. Chuck (sales manager) and Stewart were both very personable and never felt pressured to buy something we did not want. In fact, they said they would rather not make a sale than have us be unhappy with a vehicle or the process. In summary, we believe we were treated well, communicated to well, had a fair negotiation, and were delivered an excellent vehicle. We will absolutely check with Schrier again when we are ready for our next vehicle.
Our 2021 Terrain SLT is really a nice auto.

Lexus of Tucson on Speedway is the friendlist dealership
Lexus of Tucson on Speedway is the friendlist dealership I have ever been in. Everyone greets you and asked how you are doing. They all were great!
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.

Excellent experience.
Excellent experience. Mike went above and beyond to help us understand all the options and how to work them so we could utilize options that we normally wouldn’t know about. I would highly recommend Trent (and ask for Mike). They made the buying experience super easy and seamless. Thanks!

I had a rough first experience at Mac Haik Chevrolet’s
I had a rough first experience at Mac Haik Chevrolet’s service department, but Brian Caldwell, the Service Director, completely turned things around. He personally followed up the same day I voiced my concerns, sent a mobile tech to my house to handle the software update, and later arranged for a porter to deliver a loaner and pick up my truck for a roof recall and additional service. They performed every repair as promised—on time—including the roof fix, oil change, tire rotation, and a minor interior issue. Brian kept great communication throughout, even with our busy schedules, and treated my time and situation with real respect. What started as a frustrating experience turned into one of the best service recoveries I’ve ever seen. Huge thanks to Brian, his team, and Mr. Mac Haik. This is how a dealership should be run.
