Used Car Red Flags to Watch Out for When Buying a Car

Buying a used car can be a smart and cost-effective decision, but it also comes with risks if you don’t know what to look out for. Whether browsing online or viewing a car in person, there are several warning signs that should make you pause, ask more questions, or walk away altogether.

When searching on DoneDeal, be wary of listings that seem too good to be true. Unrealistically low prices for the make, model, and year of the car could signal hidden problems, outstanding finance, or even potential scams. Poor-quality photos or a lack of detailed images, especially of the interior, engine bay, and rear can suggest the seller is hiding something.

Always check the description carefully and look for the Greenlight verified tick. A vague listing with little mention of service history, ownership, or condition is a red flag. It's also worth being cautious if the seller is reluctant to speak on the phone or only communicates via message. Trustworthy sellers should be open and transparent.

If the car passes the online sniff test, an in-person inspection is your next crucial step. When viewing the car, start by checking the exterior for signs of accident damage or poor repair work. Mismatched paint, uneven panel gaps, or rust spots could indicate underlying issues. Check for excessive wear on the tyres as it may signal poor maintenance or heavy use. Inside the car, look for signs of unusual wear on the steering wheel, gearstick, and seats. If a relatively low-mileage car looks overly worn, the odometer reading may not be accurate.

Inspect the service history thoroughly. A car with no records or big gaps between services is a risk. Look for consistent mileage progression and stamps from reputable garages. Don’t forget to check under the bonnet for oil leaks, frayed belts, or low fluid levels, and listen for any strange noises when the engine is running. If you are unsure it’s wise to have the vehicle inspected by someone more experienced.

Always insist on a test drive, and avoid any seller who refuses. Pay attention to how the car drives, how the brakes respond, and whether there are any warning lights on the dashboard. If in doubt, a professional inspection from a trusted mechanic is money well spent. In summary here are the DoneDeal 5 Red Flags to watch out for!

Unrealistically low price – If the price seems too good to be true, it often is. It could signal hidden damage, outstanding finance, or a scam.
Lack of service history – A missing or incomplete service record could mean the car hasn’t been properly maintained, increasing the risk of issues down the line.
Signs of accident repair – Mismatched paint, uneven panel gaps, or overspray can indicate previous crash damage and poor repair work.
Warning lights on the dash – If any dashboard warning lights are on during a test drive, it could point to mechanical or electrical problems.
Seller reluctance – If the seller avoids questions, won’t provide a registration number, or refuses a test drive, walk away—it’s not worth the risk.
