Facebook Marketplace has become a genuine marketplace for mobile mechanic services. Some of those mechanics are legitimate, experienced, and affordable — exactly what they present themselves to be. Others are scammers who will take your money, do shoddy work, damage your car, and disappear before you realize what happened.
The platform doesn't vet either type. That's your job. Here's how to do it.
Red Flags That Should Stop You Cold
Brand-new or recently created account. Check when the profile or business page was created. An account that's three weeks old, advertising mobile mechanic services with glowing reviews, is almost certainly fake. Real businesses have a history. Scammers create accounts for each operation.
Stock photos as "their work." If the photos in the listing look like they came from a manufacturer's website or an auto parts catalog — perfect lighting, professional composition, no real workshop context — they probably did. Ask for photos of their actual workspace, tools, or a vehicle they've recently worked on. A legitimate mobile mechanic has a work truck with real gear in it.
No business license information listed. Many states require mobile mechanics to carry a business license. A legitimate professional knows this and can provide their license number. If you ask and they deflect, can't find it, or tell you "I just work for myself, I don't need one" — verify that claim yourself with your state licensing board.
Only accepts cash or Venmo/Cash App with no record. Cash isn't automatically a red flag — plenty of legitimate small businesses prefer it. But if they insist on cash only, refuse any payment method that creates a paper trail, and get evasive about why, that's a problem. Venmo's goods-and-services option offers some buyer protection; if they specifically want to use the friends-and-family option, they're trying to prevent chargebacks.
No physical address or verifiable location. Not a P.O. box. Not "serving the greater Atlanta area." An actual address where you could reach them if something goes wrong. Mobile mechanics don't need a shop, but they need a real business address associated with their license.
Can't provide proof of insurance. More on this in a separate post, but: if they can't tell you what liability coverage they carry and produce a certificate of insurance on request, don't let them touch your car.
Too-good-to-be-true pricing. An oil change for $19, a brake job for $80, a timing belt replacement for $150. These prices are not real. Either they're bait to get access to your car or your driveway, or the parts they'll use are counterfeit or stolen. Real parts and qualified labor cost money.
No reviews outside the Marketplace listing. Check Google. Check Yelp. Check NextDoor. A mechanic who's been in your area for any length of time will have a footprint somewhere. If the only evidence they exist is the Marketplace post in front of you, treat that as a warning.
What a Legitimate Mobile Mechanic Looks Like
A professional mobile mechanic has:
- A named, searchable business
- Reviews on multiple platforms that span months or years
- A business license they can cite by number
- Liability insurance they'll verify without hesitation
- A work vehicle that's actually set up for mobile repair
- Prices that are lower than a shop but not impossibly low
- A willingness to provide a written estimate before starting work
They also won't pressure you to decide immediately, won't ask for full payment upfront, and won't get defensive when you ask basic questions. Legitimate professionals expect due diligence. Scammers don't.
Trust your instincts. If something about the interaction feels off — the responses are vague, the timeline is rushed, the deal feels too easy — it probably is.
