Shopping for a GMC Yukon
This was my 1st experience with CarMax and I have absolutely nothing but WONDERFUL things to say about the entire process. Everyone that I dealt with, throughout the entire process had amazing attitudes and willing to help in any way possible. I truly felt like everyone enjoyed their jobs and their main goal was to make sure all their customers got into the vehicle that they truly wanted. I can't thank this team enough, for making our Yukon purchase as smooth as it was!

We had a great experience here, our sales professional Scott Gamble did a great job. His knowledge of his vehicles all the way down to what features came with all the trim levels made it much easier to decide. Would definitely buy from them again.

Was in New Zealand. Contacted Peter about purchasing a new 2025 RAV4. Peter arranged it and we just picked up our new car. Both Peter and Josh facilitated the on-site transaction smoothly and efficiently. This was a positive experience in every way.

oil change, repair tire monitor and purchase windshield
oil change, repair tire monitor and purchase windshield wipers to about 3 hours. Work was done very well. Walser Buick is a very popular dealership and sometimes you have to wait a bit. All is well and I will continue to purchase vehicles from them as well as servicing them.
