Hands down the best and most fair auto shop in Hamilton. I've not only bought a truck off Malcolm (Works great, was at a great price too) but I've also have had him do a ton of work to a work truck of mine as well. As a business owner it was very important that I got the truck done not only quick but at a fair price. They delivered. Again, I have nothing but good to say about O.N.S auto and highly recommend. Always friendly and always willing to work with you and get you back on the road. Just true professionals.

I brought my car to ONS to find out why there was a grinding sound coming from one of the wheels while driving. While there I asked if he could give the car a look over as I haven’t been keeping up with the maintenance and was sure I’d have a long list of things to be repaired or replaced. Within an hour Malcolm called me to let me know why my car was grinding, and that all I needed done was spark plugs and brakes. The service was quick and cost efficient.

I was brand new to Hamilton from moving from Australia looking for a new mechanic and I am so happy I found ONS!! Its is hard find someone when your new to an area that you can trust so much but he handled my car with such professionalism. My car was fixed and running better then before. The car was ready very quick and for a reasonable price. I would recommend him to all my friends and strangers and looking forward to financing a car in the future.

Excellent service! I was looking for an auto shop to have my brakes serviced and I’m very happy I chose ONS auto. They got me in super quick, explained exactly what was done, and sent a service report directly to my email prior to any work being done, which I really appreciated. I’m very happy with the service and I will definitely be back. I’d highly recommend ONS auto for professional, friendly, and efficient service!

My daughter purchased her first vehicle from Malcom. It was such a great experience. Malcom wanted it to be. He was professional and not at all a pushy salesperson. He was sincere and so very helpful. Malcom went above and beyond. He is knowledgeable on so many levels and his expertise is evident. The car is exactly what he said it was. He is worth trusting. I would have no hesitation recommending his service to anyone.

Recently bought a used vehicle from ons auto. I have dealt with them for repairs mostly over the years. They made buying a vehicle very easy and no pushy sale tactics as well They addressed all my concerns and when I received the vehicle it was better then we could have hoped. The whole process of purchasing and financing with them was easy and problem free. I would definitely recommend them to anyone.Thank you!!

I've found the staff and management at O.N.S Auto to be reliable , they go over and beyond to ensure that you are fully satisfied with the work that is done and if they identify additional causes to be concern about they notify you but take no action unless you approve the work , something I personally appreciate . I've recommended O.N.S Auto to friends and will not hesitate to do so again .

Highly recommend!!! This was the fastest and easiest car purchase I have ever experienced. The owner was very knowledgeable about the car I was buying. I didn't feel like He was trying to "sell" me on anything making me very comfortable. He was upfront and honest, which I knew because I had already done my own research on the car and price. Thanks

Malcom was a Absolute Pro. Bought a car from ONS and it was my Son’s first experience buying a Car and it was Amazing. Malcom went out of his way and replaced anything that was not to his Standard. He cares about his Customers and wants to establish a great relationship for the future of his Customers. Highly recommend. A+++

I've been going to this mechanic for about 3 years now and about 2 separate cars. They are reasonable and honest here! I spent years looking for a mechanic like this. I'm finally satisfied with my choice. I will recommend anyone to go here! You will get good quality work done and at a reasonable rate!

O.N.S Auto is the best! There’s nothing they can’t fix on your car, and they are timely and gracious to work with regardless of how big or small the job is. They’re a busy shop, but they always take the time to explain and go through all the options with you. Love having them in downtown Hamilton!

Every time I drop my car off at ONS Auto, I can feel confident and rest assure that my vehicle is in good hands. Quality service, good pricing, excellent professionalism and the mechanics always do a great job! I would definitely recommend ONS Auto to my family and friends! 5 star service!

Took my car to 4 different mechanics before ONS. No one could figure out what the problem was, or told me there wasn’t a problem. ONS found the issues within 10 minutes. Pricing is super competitive and will even let you bring your own parts.

I really enjoyed my experience here. The service was done very quickly and for a reasonable price. He put in quality parts as well, not cheap stuff. Would recommend this place to anyone looking for a good quality mechanic that you can trust.

In November 2021, ONS Auto took my vehicle as a trade in towards a new vehicle and did not payout my previous lien resulting in credit damage and the vehicle i was sold requires $7500 plus for a new engine ….. Absolute crooks

Malcolm is always our first call when we need anything done with our vehicles. ONS Auto is fast and reliable, and the prices are always reasonable. We will continue using ONS for our needs.

Just an oil change, but it was exactly the time frame they quoted me and was less expensive than a higher end quick stop lube shop would have cost. Thanks

Absolutely amazing Auto Centre, they have been very helpful from collision repairs to just your basic oil change! I am glad I’ve found this establishment

The owner was very nice to deal with and was prompt in responding to my questions! Great deal on the car I was looking for. Thanks again.

Owner is very professional and fixes cars on a timely manner! Very reasonable prices! Definently my new permanent mechanic !

I purchased a car from this dealership , and it was the smoothest process I would definitely recommend

I always receive great service, the work is done in a timely manner and prices are reasonable too!

Purchased a car from Malcolm was easy and quick. Very accommodating and knowledgeable.

My cousin referred me and I’m glad she did! Thanks for the amazing service!!!
