Makes We Service

Our Customers Say It Best!

We just had a 60k mile update on our truck with new tires. The work was done quickly and we were updated on the work. Everybody was great to deal with and they go out of their way to make sure the work was satisfactory. I would recommend them without reservation and will continue to use Tinj too for our future auto needs.

Reasonable priced..Fixed my vehecile not once but twice so far & I didn’t have appointment on 2nd vehecile. I would recommend this shop to anyone who needed a good mechanic business owner any time

If i could give him more than 5 stars I would,Im new to the area & lucky that I found a great mechanic owner. Hes a pleasant down to earth ez to talk to fellow, Not only does he explain things wrong on your vehecile he also shows you the video of it as well, gives you the best reasonable price he can give you. He takes you home if you have no way to get home..And even after his closing hours he still got my car back to me..What other Shop owner would do that. I wouldn’t take my vehecile to

What a breath of fresh air. They are polite and do what they say they’re going to do. They checked in with me to let me know what my vehicle needed, sent me a link that showed a prioritized list of items…most important to fix to less worrisome items. They gave me a free loaner car to use, even dropping it off to my house for me. Then, a week or so after I had my vehicle back (after repairs), they called to check in to see if everything was working well and met my expectations. I have had

We switched to having our vehicles serviced at Tinjtoo after having less than ideal service multiple times from the places that we normally took them to in town. Tinjtoo has been nothing been great with their customer service. They have a detailed quote that lists the issues and costs to repair, will highlight what needs to be done now vs what can wait, and include pictures and sometimes even videos of your car to show what the issues are. They have gone above and beyond in customer service wh

What a Great experience! They got my vehicle in right away, did a very thorough inspection, and went out of their way to get it fixed the next day and back to me in time for the weekend. And all with great customer service at a Very fair price. I will be back for my future service needs. Thank you Tinjtoo crew!

Service was prompt even though I limped in without an appointment. I was kept well informed along the way. They fixed the worst problem and identified others, some of which I didn’t know about. Communication about various options was very good. I intend to return for more service, in a more planned fashion next time.

Really great people and great service at Tinj too Auto. Needed a full CVT Transmission replacement in our Subaru Outback and after calling multiple places they had the best price and warranty and we’ve had zero issues with it since. Highly recommend them.

Received a coupon in the mail, went in for an oil change and ended up needing front breaks done as well. Very good service, friendly staff, reasonable pricing. I am 100% happy and plan on returning for all my auto needs. Highly recommend shop.

Very knowledgeable and honest shop. They will tell you what’s wrong, but not pressure you into any work (though if it’s a safety issue, they’ll really recommend it). I’ve been dealing with the owner for several years, even before he started this business, and he’s always been very fair with me, and gotten the work done quickly.

We just moved to New Richmond WI and we needed to find a Mechanic to work on our 1968 Camaro. The family loves the Camaro and at 57 years old the Camaro needed some work on the bushings, suspension, electrical and speedometer. Jarred and John met with us and we built a plan to get the Camaro upgraded. Jarred and John executed the plan flawlessly. Jarred and John were very easy to work with and they kept us up to date. The guys are very Professional, and they do Excellent work.

Friendly, fast, and reliable. I dropped my car off for an estimate and picked it up a few hours later with photos, videos, and explanations of the things that were wrong with my Challenger. Their quote was the lowest of three local repair shops. They were able to get my car in right away for repairs. They replaced my ball joints, tie rod end, and did an alignment. Everytime I called John was very helpful!

Great folks and great service. Went in as my steering wheel was shaking at 50+ mph, they checked it out and found out my tires needed to be replaced, ended up opting to wait on replacing the tires, also got an oil change that was quick. Super professional and courteous. Recommend if you want honest and professional service.

I own a Volvo and had to jump start it during the winter. Ever since the jump start I lost my power steering and other features. I replaced the primary and secondary batteries and the issue remained. I pride myself in resolving most automotive issues, but after replacing fuses, checking relays, and resetting the system countless times, I had to admit defeat. Tinjtoo, within a half an hour were able to resolve the issue, and at a cost of $73, I wish I had admitted defeat far sooner. The entire ex

Great guys to work with, I noticed what I thought was a transmission leak expecting the worst, called for an estimate they got me in right away, turned out to be a line leaking, while the van was there they did a complete inspection pointing out what should be fixed, even sent me pictures of what they found wrong, even the Chrysler dealer didn’t do that just quoted me an outrageous price. These guys aren’t your typical ” fix it, leave grease on the seats and steering wheel” type, they treat you

I was totally impressed with the knowledge and service that I received from John and Jared. The service was reasonably priced and was done well and with efficiency. The only problem is that I wish I lived closer to the shop! 🙂

Through service. They check out all of my vehicle and made suggestions to what should be done. They made recommendations and I chose what I wanted repaired. Highly recommend Tinjtoo Auto Repair.

I am Director of Operations for a tree service. Our trailer brakes went out on one of our trailers our employee was driving. It was about to be a horrible storm, and he got stopped by DOT. We KNEW we would be called out for storm damage work that night, so we needed the trailer fixed. I looked up mechanics in the area, and to my surprise Tinjtoo was a mobile mechanic and came rushing to save the day. I can’t describe to you how amazing this guy is, you just have to trust me when I say he is AMAZ

Very great service, was open and transparent about what was needed to be done on car. He looked out for me when I thought I had to get a strut repaired which was preferred by a mechanic and when I came in to him he let me know the worst price which was a very fair price to start with. Way less than all other mechanics and quality work! Found out I only needed a sway bar which was far less cheaper and helped tailor to my needs. He will give you what you need some on your car and not put extra on

Jarred is awesome. I was looking for a new mechanic after my previous mechanic shop kept screwing up. I sent Jared a note and he responded immediately. Took care of a job on one of my cars at my house and did an outstanding job. Pricing is spot on, he knows his stuff and you can trust him with any maintenance/repair needed. He even stayed after he was finished to talk through some future projects with some of my other vehicles. It’s nice having a honest mechanic that knows what he’s doing an

Jarred is so amazing! He is knowledgeable and responsive. We have already booked our second vehicle maintenance and all around look over everything with him. Highly recommend! He also was able to pick up and drop off our vehicle when we were down a truck! Thank you Tinjtoo Mobile Auto Repair!!

Awesome and honest mechanic! Super nice guy as well! Provided a very thorough estimate of what needed to be done. My husband has had his truck serviced there in the past and was also very satisfied with the service he received.

Jarred was awesome to work with. I had taken my car into another shop and they kept repairing everything but what was actually the problem. He figured it out within a few minutes. Great customer service also. Would highly recommend
