Mobile mechanics can be a legitimate, affordable option — especially if you can't easily get your car to a shop. But Facebook Marketplace and Craigslist have become hunting grounds for scammers who take your money, do bad work, or just vanish entirely.
Here's what to watch out for before you book anyone.
They Only Have a Personal Profile, No Business Page
A real mobile mechanic running an actual business will have some kind of online presence — even a simple Facebook business page with reviews. If you're dealing with a personal profile that went up six months ago and has 40 friends, that's not a business. That's a red flag.
No Reviews, or Suspiciously Vague Ones
If someone has no reviews at all, or their "reviews" are just friends saying "great guy!!!" — that tells you nothing. Look for specific feedback: what the job was, how it went, whether the problem was actually fixed.
Stock Photos Instead of Real Work
Scroll their photos. If it's all watermarked stock images of tools and engines instead of actual jobs they've done, they're borrowing someone else's identity. Legit mechanics post their real work.
They Won't Give You Their Full Name
If someone is cagey about their full name, won't give you a business name, or only goes by a nickname — walk away. You need a real name to file a complaint, dispute a charge, or take someone to small claims court.
Cash App Only, No Paper Trail
"Cash App, Venmo, or Zelle only — no refunds" is not a payment policy. It's a getaway plan.
Any legitimate service provider will accept multiple payment methods. Insisting on cash apps with no recourse is designed to make sure you have no options if things go wrong.
No Written Estimate
Before any work starts, you should have something in writing — even a text message — that breaks down what they're going to do and what it will cost. "I'll fix it for around $200" is not an estimate. It's a setup for a surprise bill.
The Price Seems Too Good to Be True
If someone is quoting you $80 to replace a water pump when every other shop is quoting $400, one of a few things is happening: they're planning to do it wrong, they're going to disappear with your deposit, or they'll find "additional problems" once they're under the hood.
What to Do Instead
Before you book anyone from Facebook or Craigslist:
- Ask for their full name and business name
- Search that name + your city to see what comes up
- Request a written estimate before they touch the car
- Pay after the work is done, not before
- Use a credit card if possible — it gives you dispute rights
EthicalMechanic.org exists specifically to help you find mechanics who've been vetted and reported by real customers. Use it.
If something feels off, trust that instinct. There are good mobile mechanics out there — but there are enough bad ones that you should never skip this kind of basic due diligence.
