My wife was looking to purchase a newer Toyota 4Runner &
My wife was looking to purchase a newer Toyota 4Runner & trade-in her 2015 Toyota 4Runner SR5. She was really looking for a white 2023-2024 Toyota 4Runner Limited with low miles & sand/beige leather interior. On a Friday afternoon, she saw that Beaver Toyota had one on their lot, and we called them and told them that we were coming up to take a look at it (we live 3 hours away). Kelly said that she would have it ready up- front for us to view and test-drive upon arrival. We got there about 6:30pm & talked to Zack. We went on a test-drive, and he answered our questions. We went into the dealership and began the purchasing process. From the time we arrived to the time that we drove off the lot with our 2024 Toyota 4Runner Limited, the entire process only took a couple of hours. The Beaver Toyota Dealership is a state-of-the-art facility, and I look forward to using my "Beaver Benefits" that came with our purchase to help with the maintenance and longevity of our vehicle for years to come. If you're in the market for a new or used vehicle, I highly recommend Beaver Toyota!
This truck has a jerk when changing gears sometimes.

The customer service was great.
The customer service was great. I have tow complaints: 1. A 3% surcharge when using a credit card which everyone pays with. 2. The waiting room was freezing. I know it?s extremely hot outside but it was very uncomfortable in the waiting area.
