Mechanics charge you more for parts than what you can buy those parts for online. People ask me about it from time to time. Is this a ripoff? No, it’s not.
This question usually pops up in my line of work when someone goes over a work order with a fine-toothed comb and then “checks” the prices they were charged for parts against prices on the internet. $249 for an alternator? You can buy one on Amazon for $86!
A markup on retail items—car parts or otherwise—is part of any business. And comparing Amazon prices to anything retail is misleading. My latest book (sorry not sorry for the plug) has a cover price of $39.95 but Amazon is giving them away for only $30.53.
Why is this? Among other things, Amazon does not run a local retail location with a person standing at a counter who can answer your questions.
But the parts question has a few more components. The part you get on Amazon might not be the same quality or have the same warranty as one from the local shop. The cheaper alternator cited above from Amazon comes with a one year warranty. The Ford Motorcraft alternator comes with a two year warranty.
And let’s face it: If you want that cheapo price on that car part, you have to buy it and install it yourself. While you might be fine with that, most people aren’t (hence the number of times I get asked this question.) When you pay the expert to install the part in your car, part of what you are compensating them for is what they bring to the transaction. The ease of installation (it doesn’t require you to get your hands dirty!) and the expertise. Most people would rather have the part installed by an expert who has done the installation many times before than try and do it themselves in their driveway.
And that installation quite likely comes with a warranty. The alternator dies the next day? Take it back to the shop if they installed it. You installed it? Pop the hood and start troubleshooting, Chief. Is the part defective or did you install it wrong?
I posted a question and asked guys in the industry to write and give me the lowdown on markups at dealerships and shops. Parts markups can vary from shop to shop and from dealer to dealer. Generally though, there are industry standards. What you are buying is the expertise of the shop and helping them keep the lights on and the doors open.
Would there be a markup that was too high? Of course: If they charged you $2490 for the $249 alternator, that would be a price “grossly in excess of the value of the goods.” In Michigan, and many other states, that would make it wrong. But notice the phrase “grossly in excess . . .” Simply charging you retail for a part that you can buy for close to wholesale isn’t going to break the law.
So, before you freak out when you see the price difference between the shop price and Amazon, remember that the comparison is not fair. Mechanics have to feed their kids too. And if you want the cheap price, you’re going to be doing the work yourself.
