A used car ad can have gorgeous photos, a glowing description, and a price that feels like a steal, and still be wrong. After 20 years on the dealership floor, I've seen buyers get close to driving hours for a car that wasn't what the listing said it was. Here's the checklist I run on every online listing before I'd let a client get excited about it. I work mostly with BMW and INFINITI buyers, but none of this is brand-specific.
Start With the VIN
The VIN is the first thing I look for. It's how you confirm that the car in the ad is the car you think it is, and that its description is accurate. Most listing sites require the seller to provide it, but some sellers hide it and tell you it's "for serious buyers only." That's backwards: the VIN is what a serious buyer needs in order to check the car. Ask for it. If a seller won't give you one, treat that as a red flag and move on.
Do the Photos Match the Description?
Next, look at whether the listing has real photos and a real description, and whether the two tell the same story. If the photos show what the description says, you're in the green. Pay attention to details that don't line up: a different interior color, wheels that don't match the trim, a package listed in the ad that you can't see in the pictures. Many of the features that come with a package have a button, switch, or badge you can spot in the photos, so ask yourself whether you can actually see the equipment that's being advertised.
Check Whether the Seller Is Local
Most listing sites show you results based on your location or ZIP code, so a car that's local is easy to see in person. Be careful with sellers who are far away and in a hurry. There are bogus sellers out there who list fake or stolen vehicles, and the pattern is usually the same: a price that's too good, a seller you can't meet, and pressure to send a deposit or wire money. Don't send money before you've confirmed the VIN and seen the car, or had someone you trust see it. If you want to check whether a VIN has been reported stolen or as a total loss, the National Insurance Crime Bureau offers a free VINCheck tool.
Run the History: Recalls, Service Records, and Carfax
Once I have the VIN, I check it. At the dealership, I can run it through BMW's systems to see open recalls, previous ownership, and service records, and I pull a Carfax report. Of all of those, service records and the Carfax are the two that matter most in most car purchases. A car with documented, on-time maintenance is a very different purchase from one with gaps. You can check for open recalls yourself for free: NHTSA has a recall lookup at nhtsa.gov/recalls where you can enter a VIN.
When Two Similar Cars Have Different Prices, Find Out Why
Listing sites let you sort by price, mileage, year, or distance. One of the best habits you can build is to find two or three very similar cars (same model, similar packages, similar mileage) and compare them. If the price difference stops you in your tracks, don't just take the cheaper one or assume the expensive one is overpriced. There is almost always a reason. It could be accident history, a missing package, tire and brake condition, the number of owners, or a dealer fee. Once you know the reason, you can decide whether it's worth paying more, or whether the cheaper car is a bargain or a warning.
Read the Description, Not Just the Photos
Most people look at the pictures and the headline details and jump. The description is where mistakes hide, and so are the details that decide whether it's the right car. Here are two real examples, with details changed.
A DMV client of mine found a car at a used car dealership in Florida. Everything checked out. The dealership had advertised it beautifully, with 4K photos that captured every detail, and the description was on point. But when I pulled the original build sheet to see which packages and features the car left the factory with, the ad listed three packages the car didn't have. The car itself was a good car, and I'd have encouraged him to buy it if the dealership had corrected the price. But once he knew the ad was misleading, it left a bad taste in his mouth, and he decided not to buy. He thanked me for catching it.
Another client found what looked like a unicorn: the right color, the right packages, the right price, and the pictures looked perfect. But one photo didn't look familiar to me. It showed a different car. If I hadn't caught it, he would have driven to New York to buy it.
Sellers don't need to exaggerate a BMW to sell it, because buyers who know the brand will spot a bad listing quickly. So match the packages and features in the ad against what you can see in the photos and, if you can, against the car's original build sheet.
Ask for the Out-the-Door Price
The advertised price isn't what you'll pay. Ask for the out-the-door price, which includes the dealer's fees, taxes, and registration. If you're buying in DC, Maryland, or Virginia, the taxes and fees differ, so run your own numbers with the DMVCalc calculator before you commit.
Want a Second Set of Eyes?
If I can't sell you a car, I'll help you with the one you find online. Paste the listing link and your contact info into Car Finder, and I'll review the listing, including the price, the vehicle history, the options, and anything that looks off, and get back to you before you commit.
