The service advisors at Wackerli GMC are top notch! I always know I am getting the best service for my vehicle! The technicians are excellent.

DealerRater Mar 26, 2025

My new car buying experience was positive and I would recommend Wackerli Auto Center. I had the pleasure of working with Chris and Teagan who both were very personable, professional, and transparent during the entire process. The pre-approval, loan, registration and delivery process was simple, straightforward, and enjoyable. Thank you!

Facebook Oct 30, 2024

Teagan was beyond helpful and extremely professional during the sale of our new 2025 GMC. Highly recommend!

DealerRater Aug 25, 2024

They have always done an excellent job. Very reliable and efficient. Thank you to the entire team

DealerRater Aug 5, 2024

I recently bought a new truck at Wackerli. This was my first time doing business at this dealer. Teagan and the Wackerli team made it quick and easy. They worked out a trade with another dealer out of state so I could get the exact truck I wanted. I appreciate their effort to make that happen so quickly.

DealerRater Jun 3, 2024

The salesman Jason was amazing!! Was helpful before during and after the sale great guy will definitely recommend him to anyone I know

DealerRater May 31, 2024

I love my 2024 Buick Envista. Jason was our salesman. His knowledge of the vehicle and genuine friendliness shines through. I would recommend him to anyone looking to have a great experience where most tend to expect the opposite. Jason and Wackerli get a 10 out of 10.

DealerRater Apr 1, 2024

My family has always been loyal to Wackerli Auto Center. I figured I'd give it a go. Jason in sales introduced himself as I was exiting my car. We talked for a bit and he is a genuinely friendly guy and he knows his stuff. I will continue in my family's footsteps with Wackerli and I will work exclusively with Jason H.

DealerRater Apr 1, 2024

Very pleased with salesman Jason. First thing I noticed was how friendly and genuine he was. I don't think he ever stopped smiling. He answered all of my questions(I had a lot of questions) and was very patient. I've already referred 2 friends and will continue to do so. Thank you Jason H.

DealerRater Apr 1, 2024

5 stars for Wackerli Auto Center. 10 stars for Jason in Sales. I highly recommend this dealership and this salesperson.

Facebook Mar 31, 2024

Come take a look at our best selection of trucks in over 3 years. New vehicles on the showroom side of Holmes and we've re-opened the Pre-owned lot across the street. Stop in, ask for Jason, and let me go to work for you.

DealerRater Mar 31, 2024

I stopped in to browse the inventory. I was greeted by Jason, a down to earth, funny, and friendly salesperson. I told him my budget and my can't live without features. He actually listened and showed me a Buick Envision. It covered my features and most importantly fit my budget. Thank you Jason Haring and management.

DealerRater Mar 29, 2024

Great service. Jason was very friendly and informative. Knowledgable about the vehicles. Committed to making sure we are taking care and get what we need..

DealerRater Mar 28, 2024

From sales to service and everything in-between... Wackerli Auto is first class. As a customer you can expect 110% from the whole staff. When you leave you feel like family.

DealerRater Mar 5, 2024

Mike and the rest of the service department crew are always so helpful and accommodating! Whenever I call or take my Yukon for service, they keep me updated and are quick to answer any questions or concerns that I might have.
