Reading car listings the right way: How to tell good offers from bad ones

The problem with online listings

Online platforms like mobile.de, AutoScout24 and Kleinanzeigen.de have democratised the used-car market — with a single click you can compare hundreds of offers from across the region. But that same convenience has a downside: listings cost little and can promise a lot without delivering much.

Many buyers only discover at the viewing that the vehicle doesn't match the described condition. A missing maintenance history, concealed accidents, cosmetic defects that weren't visible in the photos — all of this leads to wasted time and frustration. A systematic analysis of the listing before making contact significantly reduces this risk.

Step 1: Read and analyse the vehicle description

The quality of the description is the first and most important quality marker of a listing. A good listing states:

• Make, model, engine and year of manufacture clearly and without contradictions
• Mileage at the time of the advert
• Number of previous owners
• Details about the maintenance history: service booklet present, last roadworthiness inspection (Hauptuntersuchung), and where applicable the last service
• A list of features with concrete details (air conditioning, navigation, heated seats — not just "fully loaded")
• Known defects or signs of wear

If essential details are missing — especially regarding the maintenance history and known defects — that's a warning sign. Sometimes it's sloppiness, sometimes it's intentional.

Pay attention to the wording: vagueness can be deliberate. "Vehicle was serviced regularly" without a service booklet, "minor signs of wear" without photos, or "accident-free according to the previous owner" (instead of: demonstrably accident-free) are phrasings you need to ask about.

Step 2: Examine the photos closely

Photos say more than a thousand words — when they exist. When analysing the images, the following applies:

Quantity: Reputable offers show the vehicle in full — all four exterior views, the interior front and rear, the engine bay, the boot, the tyres and, where relevant, detail shots of defects. Listings with two or three photos that only show the vehicle from one side are inherently suspicious.

Quality: Photos taken in poor light, from unfavourable angles or at low resolution can hide deficiencies. Professional-looking photos in an empty car park or a garage are neutral — what's striking is when the same side or perspective is consistently missing.

Content: What don't the photos show? If there are lots of exterior shots but no interior photos, that's a hint the interior has something to hide. The same applies to missing engine-bay photos.

Bodywork in photos: Look closely at the paintwork — colour inconsistencies, uneven panel gaps and visible dents sometimes show up in photos already, once you know where to look.

Step 3: Put the price in context

A conspicuously low price is rarely a bargain — more often it's a warning sign. Compare the offer with similar vehicles on the platforms: same make, similar year, similar mileage, comparable equipment.

If the price is well below the market average, the question is: why? Possible legitimate reasons are an urgent sale situation, known defects (which should then appear in the listing) or missing features. If there's no apparent reason for the price reduction, caution is warranted.

Conversely, inflated prices aren't automatically a quality marker either — even private sellers can have unrealistic price expectations.

Step 4: Assess the seller

The platform often indicates whether you're dealing with a commercial provider or a private individual. Both can make reputable offers — but the conditions differ:

Commercial dealer: Has statutory obligations (warranty, price-disclosure requirements) and can be assessed via reviews on the platform. A dealer with many positive reviews and a clear returns policy is a good sign.

Private individual: No warranty claim after the purchase if it is contractually excluded. Reviews are often unavailable. On the other hand, the price is usually lower and there's more room to negotiate. Your own need for careful inspection rises accordingly.

With private sellers, it's worth asking how long they've owned the vehicle: someone reselling a car after just a few months may have quickly discovered a problem.

Step 5: Making contact — the most important questions

A phone call with the seller delivers information that no listing can fully cover. Important questions:

• Why is the vehicle being sold?
• How many previous owners did it have, and how long have you owned it?
• Has the vehicle been in an accident — even a minor one?
• Is there a complete, gap-free service booklet? When was the last workshop appointment?
• Are there any currently known defects or faults?
• Can I see a current HU report?
• Where is the vehicle located, and when can I view it?

While you do, pay attention to reaction and tone: a reputable seller answers willingly, doesn't get impatient with follow-up questions and doesn't dodge them. Anyone who hesitates when asked about known defects, or replies "everything runs perfectly" without further explanation, warrants scepticism.

Always trust your gut: if a conversation feels odd, there's often a reason for it.

Requesting documents before the viewing

Reputable sellers will send you photos or scans of the key documents on request — saving you an unnecessary trip. Ask for:

• The registration document (Zulassungsbescheinigung Teil I): does the vehicle description in the listing match the document?
• The current HU report: when was the roadworthiness inspection, are there any recorded defects?
• The service booklet or maintenance records: are the stamps, dates and mileages plausible?

If the seller can't produce the service booklet or it has "gone missing", that's a considerable mark against their credibility — and it should be reflected in the price.

Warning signs at a glance

The following points should prompt heightened caution:

• Very few or one-sided photos
• Photos show visible defects that aren't mentioned in the description
• A price well below the market average with no apparent justification
• No service booklet or a patchy maintenance history
• Evasive or nervous reactions to standard questions
• No proof of previous ownership or an untraceable vehicle history
• Pressure to buy quickly ("I have other interested buyers")
• Cash payment only, no purchase contract wanted

None of these signals is, on its own, proof of a bad offer. In combination, however, they paint a clear picture.

Listing check: when you'd like a professional assessment

If you've found a promising offer but aren't sure whether the listing reflects the vehicle's actual condition, checkdenwagen offers a listing check. Experienced team members conduct a structured phone call with the seller and record all the details relevant to your purchase decision:

• Accident-free status and accident history
• Maintenance history and service record
• Known defects and repairs
• Completeness of the vehicle documents

The result: before the viewing, you know whether the offer is worth a closer look — and you save yourself needless trips to vehicles that don't live up to what the listing promises.
