Determining the value of a used car means bringing together two perspectives: the theoretical market value and the actual vehicle condition. Valuation portals such as DAT, Schwacke or market analysis on the major vehicle marketplaces show what comparable vehicles with similar equipment and mileage currently cost — that produces a market-price range. How far the specific price sits within or outside that range is decided by the vehicle condition: prior damage, overdue maintenance, tyre condition, equipment features and whether a valid roadworthiness inspection (HU) is in place. As a buyer who walks into a negotiation with an independent inspection report, you have concrete facts instead of estimates — and therefore a factual lever for a price adjustment when defects are documented.
Determining a Car's Value: Market Value, Depreciation and Price Negotiation at a Glance
Whether you want to buy or sell: knowing the real value of a used car is the decisive step before any deal. Valuation portals, market data and your own look at the vehicle condition all work together — and an independent on-site inspection gives you the factual arguments for the negotiation.
Why both market value and vehicle condition matter
A listing price is, at first, only the seller's opinion. Whether that price reflects the actual value depends on two factors: the current market price for comparable vehicles and the specific condition of the vehicle on offer.
Market price can be estimated using valuation portals or by comparing listings on the major vehicle marketplaces. Mileage, date of first registration, equipment packages and region all play a part here. Portals such as mobile.de, AutoScout24 or the valuation tools from DAT and Schwacke provide orientation — but not a single point figure, rather a range.
Vehicle condition is what a listing price barely reflects. Does the vehicle have repaired prior damage? What is the tyre condition? Are there outstanding repairs needed? When was the last roadworthiness inspection (HU), and what did it find? Photos and descriptive text often don't fully answer these questions — an independent look on-site does.
Understanding depreciation: why used cars lose value at different rates
Not all vehicles lose value at the same pace. Brand reputation, the demand situation, the strength of the new-car market and a model's popularity all influence how steeply the depreciation curve runs. Models with high demand and low used-car supply hold their value better; vehicles with a high new price and low resale demand lose value faster.
As a rough guide: the percentage loss in value is greatest in the first few years. After roughly five to eight years the decline slows — the vehicle has already put most of its market-value loss behind it. That explains why well-maintained mid-age vehicles with a complete service history often offer particularly good value for money.
A basis for negotiation: what an inspection report is worth
A documented defect isn't a matter of likability — it's a factual argument. Anyone who walks into a negotiation with an independent inspection report is talking about facts instead of opinions. The inspection protocol names concrete findings: paint deviations, tyre condition, technical irregularities, overdue maintenance. Every documented point that demonstrably costs the seller something is a legitimate reason to adjust the price or demand rectification.
A seller who offers an on-site inspection signals trust — and thereby justifies their price more easily to sceptical prospective buyers.

Frequently asked questions about value, price and market valuation
There is no single exact figure, only a market-price range for comparable vehicles. Valuation tools such as DAT or Schwacke, along with a comparison of current listings with similar equipment, mileage and date of first registration, define this range. The vehicle's actual value is then determined by its condition: prior damage, service history, tyre condition and additional equipment push the price within — or outside — that range.
