2026 Auto Parts Store Reviews

Here you can see how Autohaus AZ and Auto Barn match up head-to-head in a battle for the Best Auto Parts Stores in 2026.

Autohaus AZ

  • Pricing from from $51.99 to $157.99 for researched parts
  • Returns within 30 days with fees
  • Focuses entirely on European cars

Autohaus AZ is an auto parts store specifically for European cars, offering all OEM parts at wholesale prices. This is the primary feature that keeps it from being a lower-rated auto parts store when considering the customer complaints and low BBB rating for this retailer. With repeated issues of slow delivery times and poor customer service, Autohaus AZ isn't a fan favorite, but its unique focus and OEM inventory rescue it from earning our absolute lowest rating.

Winner

Auto Barn

  • Pricing from from $91.95 to $1,123.95
  • Pricing for wrench sets from $21.95 to $219.95
  • Returns within 30 days

Auto Barn is an auto parts store that sells both standard mechanical parts for upgrades and repairs, as well as decorative accessories or interior detailing supplies to keep your car spotless inside and out. While the site is a little trickier to navigate than our top picks, it has a reliable reputation for sending parts that work and are easy to install. For these reasons, it earns an above-average rating in our review.

Owning a car means maintenance and repairs will come due sooner or later, and plenty of drivers tackle them themselves to save hundreds - even thousands - over the life of the vehicle. If you're going the DIY route, you'll need the right parts and tools - just like a neighborhood mechanic - to keep your favorite machine running smoothly (or finally silence that annoying ticking noise). Before you dive in, a quick check of the service manual and a trusted tutorial can help you gauge the job and avoid surprises.

Not long ago, getting parts meant driving to the local counter and hoping they had the right piece. For anyone who isn't a pro - and especially many women who've felt judged or talked down to - that experience can be intimidating. Now, online auto parts stores have changed the game, letting you compare options, check fitment guides and reviews, and order exactly what you need. Many even suggest compatible tools and how-to resources so you can finish the job with confidence.

Shopping at an online auto parts store makes it easy to confirm you're ordering the right parts for your exact vehicle, all without leaving the couch. VIN lookups and smart search tools handle the fitment checks for you, taking the hassle out of the process. Need a fresh set of tires, a turbo kit for your already over-taxed hatchback, or a metric wrench for those Euro bolts? It's all a click away. You can also compare prices and read real customer reviews before you buy, so you can shop with confidence. It's faster - and far less stressful - than wandering the aisles, and it keeps your project moving.

Buying auto parts online is often cheaper than picking them up in-store - even when both options come from the same company - because there's more competition and less overhead per part. On top of the lower prices, you can have everything shipped straight to your door. It's smart to compare sellers and factor in shipping and return policies, since those details can make a good deal even better.

With the right parts in hand and your go-to repair YouTuber queued up, you can dive into DIY car work fast. Just remember, auto parts stores aren't all the same - prices, quality, and return policies can vary more than you'd expect. Before you buy, check reviews, ask about warranties and fitment guarantees, and pick the shop that'll stand behind you if the job doesn't go as planned.

Whether you're shopping for brand-new factory components or certified pre-owned parts, aim for the best quality you can find. There are deals all over the internet, but choosing a seller you can trust matters most - for your wallet and your safety. Before you check out, scan reviews, return policies, and warranty details to confirm the parts are legit and will fit your vehicle.

If you're ready to get going on your next car project, but aren't sure which retailer to trust as your top auto parts store, we've done the hard work for you - so hopefully the process of getting your auto parts will be simple. There's enough stress when you're working on cars, and auto parts should be the easy-breezy step. Here are some factors you can consider to make sure you're getting the best auto parts from the best retailer on the market:

So, if you're ready to dive into your next project for maintenance or upgrading your ride, you've got the tools at your disposal (literally): Top Consumer Reviews has researched and ranked the best options for auto parts stores available. Now, you can grab your parts, tools, paint, and more. Whether you're restoring an old Camaro (good luck) or just trying to fix your favorite ride, there's an auto parts store out there to help you get the job done. And try not to lose your 10mm this time!

Auto Parts Store FAQ

What types of auto parts can I purchase online?
You can buy just about every part and product related to the functioning of your vehicle or other machinery from an auto parts store. From alternators to belts, and hoses to gaskets and shocks, you can replace pretty much anything you need in your car from the inside out. Take advantage of the knowledgeable customer service teams, "How To" guides, and other services made available by auto parts retailers to make your online shopping experience successful.
What if I am not sure which auto part I am looking for?
If you're experiencing trouble with your vehicle, but aren't sure what you need to fix it, you have a few options. First, you could take it into your local auto shop and have them check it out. The mechanic will be able to give you the exact part and specifications of what you need to purchase online. Your other option would be to chat with an auto parts representative through an online retailer. They are knowledgeable and helpful in guiding customers in the right direction to get their vehicles fixed.
How do I ensure that I purchase the right auto part?
If you chat online or call the auto parts retailer to describe the part you're planning to buy, they can help make sure it's the one you need. There are also detailed descriptions of each product listed online that should give enough information for customers to make educated purchases. If you realize that you need a different part after you've already submitted an online order, you can usually return or exchange your part for the right one!
Can I order auto parts online but pick up in-store?
Yes! Many online auto parts retailers have an in-store pickup option that is fast and convenient. You'll simply order online and head straight to the store to pick it up. Some auto parts stores will even bring your purchase outside to your car, so you don't have to go into the store! This ensures you get the products you need same-day and as an added perk, you save on shipping costs.
What is a refurbished auto part?
Used auto parts are often referred to as remanufactured or refurbished. This means that it was professionally remanufactured to meet industry standards and work like new. They may be less expensive than a new auto part and often come with warranties.
What is the difference between OEM and aftermarket auto parts?
OEM stands for "original equipment manufacturer". This label means that a part was manufactured by the maker of your vehicle. It was made specifically for your make and model. An aftermarket auto part is equally as effective, may cost less, but was made by a third-party for the purpose of replacing damaged parts.
Should I buy new or used auto parts?
If you have a brand-new vehicle or need a critical part replaced, it is usually recommended to buy a new part. For simple parts with shorter shelf lives, buying a used or refurbished part is a good alternative. It is best practice to consult your mechanic when making this decision and checking the part's price, warranty, and return policy before purchase. As long as you're shopping online from a reputable auto parts retailer, you will be able to get your needs met with confidence.
What do I do with old or defective auto parts?
You can either take old auto parts to a metal recycling center, donate them, or sell them to a used auto parts store. Some used parts retailers will pay cash on the spot for scrap metal. This is a great way to earn a little extra cash to put toward the new auto parts you need to purchase online.
