One of the biggest concerns to customers when buying used parts is the warranty. People want to know if the company is willing to stand behind the product. As a consumer, you may wish to know that Rectangle Auto Supply pre-tests all of its engines and warranties them for more than the industry standard.
Our Auto Service department prides itself in fast courteous service. We clearly understand your need to get your vehicle back on the road as soon as possible. Maintaining the latest equipment available to fix your problem right the first time is the key to our success. We have made special arrangements with Canadian Roadside of St. Catharines to provide our customers with added great service.
Pick through our huge inventory of quality new & used auto parts for sale in St. Catharines. Allow our friendly and knowledgeable staff help you find the right auto part at the right price. Great place, awesome service. I have been using Rectangle Auto for 20 years and there the best place in St. Catharines for used auto parts.
Rectangle Auto Supply understands that tires are the most important safety feature of your vehicle. We offer a wide selection of quality used tires & wheels in St. Catharines that ensure optimal gas mileage, top performance and above all, safety for your ride. I've purchased tires for my car and my daughter has also purchased tires and had some work done.
Aftermarket auto parts refer to those car parts that are manufactured by a company other than the original manufacturer of the car. The parts manufactured by the original car manufacturer are known as Original Equipment Manufacturer or OEM parts. Aftermarket car parts are used by auto enthusiasts to perk up the performance or appearance of their vehicles.

I have been going to this place for years
They have replaced all for sets of tires, replaced the back blinker light and even my front breaks
On my last interaction, what I can only imagine everyone should know, their mechanics striped my lock nut with an impact drill. So when I went to take my tires off to replace the back brakes, the lock nuts would not turn ensuring the nuts can’t come off.
Today when I called them to explain the situation, not only did they not even come close to making this right but refused to take any blame saying those lock nuts strip so easily.

Great bunch of people to deal with. Quite busy usually, so plan on maybe being there for a bit. No different wait than other places.

Quick and helpful. As always, with used stuff you might just need to return an item if it doesn’t work, as was my experience

My experience at this business.
I called at 4:30pm today ordered some parts and requested it be left outside after business hours.
I arrived around 6:40pm and found out that one of my parts was wrong.
Dave who happens to work there was more than helpful and took the time outside of his work hours to accommodate and move 3 vehicles to check if the correct part was available on a second parts vehicle. Sure enough, right component was identified and Dave was more than willing to take it off at 7 pm on a Tuesday. Saved me a 3 hour drive up and down.
Dave took time out of his day to make things

I was very surprised by the cost for the amount of work they did. Friendly atmosphere, when the mechanics are happy you know it's a top knotch shop! I will no doubt be returning for future repairs.

I've been a customer of Rectangle for many years. I have used them numerous times for windshield replacements, as they have consistently been the lowest price out there. I didn't think twice about price shopping the last time I needed a window. Great customer service, and always friendly and helpful. I have also been a customer for used rims and winter tires. They have a HUGE selection of nearly-new tires, full sets for your vehicle at a great discount over new prices.
Check them out, you won't be disappointed!!
Thanks for your help with my Ridgeline windshield.

Purchased a used vehicle. I had trouble right off the bat and while I will definitely give credit to Marcel for always being polite and helping me with certain issues, there were issues I brought up that were… brushed off and at the end of it all I had the vehicle 364 days and on the 365th, the transmission blew and I now have no vehicle at all. To say I'm unhappy is an understatement
