On 6/8/2026 blondeandbeyond Salon had this to say:
Great experience! The team was professional, easy to work with and completed the repairs on my vehicle quickly. The quality of the work was excellent and everything was handled smoothly from start to finish. I would definitely recommend them.

On 7/7/2025 Brandi B. had this to say:
1st Ave Auto is great, and Tom is so honest and upfront with you, I love it! I took my car there for a "clunking" in the front wheel...lo and behold it was due to my less than stellar driving....eeks! Tom knew almost exactly what I did without me telling him...there's a reason they are in the business they are in! I was lucky that there was no damage, and nothing looked out of place or loose per Tom's assessment. I was in and out in about 20 minutes - the service was wonderful! I appreciate having a locally owned auto shop right down the road from me. I will definitely be going back and hopefully not because of my less than stellar driving. ;)

Once you go to 1st Ave. Auto you won't take your vehicle anywhere else. Best in Wausau.

Tom did a major fix on our daughter's HHR. It was less than we expected and he did a great job. We will definitely be using 1st Ave. Auto again!
