eclipse_images · Getty ImagesThink about the last time that you took your car in for routine maintenance. Did you go in for a simple oil and filter change, then get hit with "critical" repair recommendations that would cost you another $900? If that sounds familiar, you're not alone.According to a survey by AAA, two in three U.S. drivers say they don't trust auto repair shops. The most common complaints are about overcharges and unnecessary service recommendations.The question is, which type of shop — dealership, auto chain or independent mechanic — is most likely to pull those types of shenanigans on you, and why?Dealerships: The Most Expensive LaneMany Americans think of their car dealership first when it's time to get their car serviced. This is in no small part due to marketing. Dealerships often provide perks like nice waiting areas, free coffee and snacks to entice vehicle owners to come back for service.AdvertisementAdvertisementBut dealerships are typically the priciest place to get your car serviced. Service department margins typically run between 45% and 55%, according to McKinsey. This means they're extremely profitable for dealers.Most dealership technicians work on flat-rate pay. Regardless of how many hours they work, they'll get paid based on a predetermined per-project rate. In that type of pay structure, mechanics are incentivized to work quickly and generate additional billable repairs.Many service advisors, the friendly faces that stand between you and the actual mechanics, work on commission. The more they can get you to spend, the more they may earn themselves.Dealerships may offer an advantage in terms of warranty work or complex electrical issues that average mechanics aren't familiar with. Just go in knowing what your car actually needs or else you leave yourself open to additional repairs.Auto Chains: Low Price in, Bigger Bill OutService chains like Jiffy Lube and Midas offer convenience and low entry-level prices, often at a discount of 50% or more from dealership prices. The problem is that the low price you get when you walk in the door isn't always what you pay by the time you walk out.AdvertisementAdvertisementAuto chains aren't necessarily deceptive. Many provide honest, top-quality work. But there are some documented records, such as from NBC4's I-Team investigation, of quick-lube shops recommending transmission fluid changes and air filter replacements on vehicles that didn't need either. Some shops were caught charging for work they didn't even perform. Part of the problem is that service advisors at chain locations typically work on commission, according to the investigation. This means the person writing up your service order has a direct financial incentive to add items to the bill.On the legal end, the California Attorney General's office sued 22 quick-lube locations following more than 30 undercover sting operations. Some chains were accused of advertising cheap brake specials to draw customers in and then charging hundreds more for unnecessary repairs.For a basic oil change, chains are often fine. In many cases, you can save a lot of money. But take it upon yourself to know your actual service intervals from the owner's manual, and treat every add-on recommendation as optional until you've confirmed it yourself.Independent Mechanics: Worth the EffortIndependent mechanics rely extensively on word-of-mouth. They don't have a built-in customer base like dealerships, and they don't have the advertising dollars that national chains do. What this means is if they take advantage of their customers, they may lose out on years of referrals.AdvertisementAdvertisementBut you'll still want to vet an independent mechanic before you simply trust every recommendation. Work with a mechanic on the AAA Approved Auto Repair network, or one who has a certification from the National Institute for Automotive Service Excellence. Certified technicians must pass standardized exams and renew their credentials on an ongoing basis.When you work with a mechanic for the first time, start with something minor, like a tire rotation or an oil change. Get a written estimate and see if you get up-charged for services you don't even need, and ask to see replaced parts when a job is done. If the technician can pass all of these tests, you're working with someone reputable.This article was provided by MoneyLion.com for informational purposes only and should not be construed as financial, legal or tax advice.More From MoneyLion:AdvertisementAdvertisementLooking to Buy Investment Properties?
