Buying a Used Car Off Facebook Marketplace or KSL: How Not to Get Burned

Updated October 5, 2026 · By Auto Ally

Facebook Marketplace and KSL are where a lot of the best used-car deals in Utah happen, and where a lot of the worst ones hide. Private sellers are usually honest. But private sales are almost always as-is, with no warranty, no return window, and nobody to complain to after the money moves. That makes the work you do before paying the whole game.

Here’s how I’d approach it.

Start with the listing

Before you message anyone, read the listing critically:

• Photos. Real photos of the actual car, from multiple angles, with the dash lit and the odometer visible. Stock images, blurry photos, or shots that avoid one side of the car are worth a question.
• Price. A car priced well below comparable listings isn’t a bargain until you know why. Sometimes there’s a reason like a rebuilt title or a mechanical problem, and sometimes it’s bait.
• The VIN. Ask for it. A seller who won’t share the VIN isn’t taking you seriously. Compare it with the one in the listing photos if there are any.
• The story. “Selling for a friend” or “just flipping it” are the kind of lines to ask follow-up questions about.

Spot the curbstoner

A curbstoner is someone who buys cars cheap and resells them as if they were a private owner, so there’s no dealer license, no accountability, and often no real knowledge of the car. Signs include:

• The seller has several cars listed at once.
• The name on the title doesn’t match the person you’re talking to.
• Vague answers about how long they’ve had it or why they’re selling.
• The title is an “open” or reassigned title, meaning the previous owner signed but the seller never registered it in their own name.

Honest sellers can be disorganized too, so none of this is proof by itself. But if the name on the title doesn’t match, treat that as a hard stop until it’s explained.

Check the title and the VIN yourself

Don’t take anyone’s word for it:

• Ask to see the title in hand, and make sure it’s in the seller’s name.
• Match the VIN on the title to the VIN on the dash and the door jamb sticker. Mismatches are a walk-away.
• Look for a brand on the title such as salvage, rebuilt, or flood. A branded title isn’t automatically bad, but it changes the value and the risk, and you want to know before you fall in love. If it says rebuilt, our rebuilt-title inspection is built for exactly that.
• Ask whether there’s a lien, and if so, how it will be paid off at the sale.

A vehicle history report helps with title events, reported accidents, and mileage records. It only knows what’s been reported, though. It can’t see the car.

Meet and look at it in daylight

Look at the car in good light, not a dim garage. Walk around it: panel gaps, paint differences, tire wear, fluids on the ground, a musty smell, warning lights on startup. Ask for a cold start. Take it for a drive. Pay attention to how it shifts, tracks, brakes, and sounds.

A test drive is worth doing, but it’s ten minutes behind the wheel. It tells you how the car feels, not what’s under it or what the computer has stored.

Get it inspected before you pay

This is the step buyers skip because they feel awkward asking a private seller, or because someone else is “interested.” It’s the step that matters most.

Tell the seller you’re interested and you’d like an independent inspection before you commit, and ask when that can happen. A reasonable seller says yes. Our inspection comes to the car: we get under it, scan the computers, road test it when conditions allow, document everything with photos, and give you a clear Buy / Caution / Walk Away recommendation. You can see what the result looks like in the sample report.

If a seller refuses any inspection, treat that as an answer. A good car doesn’t need that much protection from a second look.

Pay safely

• Don’t pay a deposit before you’ve verified the title and had the car inspected.
• Avoid wire transfers, gift cards, and payment apps with no recourse. A cashier’s check or a transaction at your bank, where the title can be signed and checked on the spot, is much safer.
• Fill out the paperwork carefully and complete the title transfer promptly.
• Never pay for a car you haven’t seen in person, no matter how good the photos look.

When to walk away

You don’t owe anyone a purchase. Walk if the name on the title doesn’t match, the VIN doesn’t line up, the seller blocks an inspection, the price drops suspiciously every time you ask a question, or the story keeps changing. There’s another car.
