Pros: 1) Base prices were competitive 2) They had the Uhaul and equipment I was looking for 3) They were open on Memorial day 4) Customer service was just fine 5) You can drop the truck (and keys) off after hours with no penalty 6) They're right next door to a quick trip gas station, so filling the tank back to where you got it can literally be the last thing you do before dropping it off. Cons: 1) If you have a local trip (in my case, less than 20 miles), it's considered a local trip, not a one way trip, so you'll have to bring the Uhaul back to this location. 2) In addition to the base price, you get charged by the mile. Despite the cons, I got what I needed and didn't walk away upset. If you need to move and are in the area, Swanson's Auto Buying Service may be your go to.

All he said was 2024, get out see you next year. And he slammed my car door and that made me mad. Like what the actual heck.

He use to be the one to pick me up at my home and bring me to pick up my car. Or take me home if my car had to spend the night. He was so young and eager to learn now he has 4 kids! I value their honesty especially being a female and a senior bc we all know how auto places try to rip off women and senior. They do not pressure you to get anything done but they explain in detail what needs to be done. Robert is an employee that is very personable and goes in depth letting you know what is wrong or what could go wrong if something isn't taken care of soon. I highly recommend this place if you are looking for an honest reliable auto repair/ service place. After my dealership warranty expires I always bring my vehicle here even for oil changes and they take excellent care of me! I highly recommend Nobody's!

Unfortunately, instead of a simple service, which should have been an oil change and a GO . I had an oil change an a TOW. My vehicle required a tow immediately after the oil change was completed. I was advised that I would be reimbursed for the cost of the oil change as well as the repair expenses that resulted from the service error. My out-of-pocket costs have exceeded $750. I was initially asked to provide a repair estimate, which I did, and later instructed to submit the final repair invoice, which I also provided. Despite following these instructions, I have yet to receive reimbursement. I have reached out multiple times to District Manager Cody Willsey and to the corporate office by phone and email, but my inquiries have been ignored. I would rate the service a zero however that option isn't available so I selected one star which is not my preferred rating.

We brought our truck in for a cooling/heating issue, which the shop repaired. However, the overall…read moreexperience raised serious concerns about their judgment and professionalism. Without our authorization, the shop added brake fluid, claiming the brake pedal went to the floor when they moved the truck into the bay. This was never discussed with us beforehand, nor were we given the opportunity to approve or decline the work. More troubling, within about a mile of leaving the shop, we experienced a complete brake failure. This created a dangerous situation that should never occur after a vehicle has just been serviced. When we contacted the owner, he claimed he had informed us there was a brake shop next door if we needed further service. That statement is simply not true--no such information was provided. While the original issue was fixed, the lack of communication, unauthorized work, and the safety risk we experienced afterward are unacceptable. We strongly recommend others proceed with caution and ensure all work is clearly authorized and explained before service is performed.
