What Does a Car Value Appraisal Cost? Prices and Services at a Glance

The costs of a professional value appraisal are often confusing in Germany, since many appraisal firms charge based on time spent or the determined vehicle value. DIAVAG breaks with this tradition and relies on a transparent fixed-price model. For a conventional car with a combustion engine or hybrid drive, the price for a standard appraisal is auf Anfrages. This amount covers all costs, including the appraiser's travel within the areas of Hamburg, Berlin and Munich. There are no hidden fees for documentation or delivery of the digital appraisal.

This fixed price includes a comprehensive technical inspection. The appraiser uses calibrated hardware such as a coating thickness gauge to identify repaints and an OBD2 diagnostic device to read the fault memory. Standardized photo documentation ensures that all value-relevant features and any defects are completely recorded. The finished PDF appraisal is signed by a senior inspector and is BVSK-compliant, ensuring acceptance by insurers, banks and in legal disputes. For private customers, this provides the certainty of knowing exactly what investment is necessary for a reliable vehicle appraisal.

For electric vehicles (BEV) and special high-value assets, the fixed price is auf Anfrages. This surcharge compared to the standard appraisal is technically justified. The heart of an electric car is the traction battery, whose condition (State of Health, SoH) significantly determines the residual value of the vehicle. While conventional inspection organizations often only carry out a basic diagnosis, DIAVAG's premium appraisal includes the so-called Premium Battery Test. This involves analyzing deeper parameters such as cell balance, actual kWh capacity and charging curve. This data is essential for a buyer or seller of a used electric car, since a worn-out battery can massively reduce the vehicle's value.

This premium rate is also applied to other complex assets such as home storage systems or particularly high-value vehicles. The increased inspection effort and the use of specialized diagnostic software justify the 100-euro difference. In return, the customer receives a detailed evaluation of battery health that goes far beyond the standard displays in the onboard computer. This is particularly important with regard to the upcoming EU Battery Passport, which becomes mandatory from February 2027. DIAVAG is already preparing its appraisals today for these regulatory requirements in order to guarantee long-term usability of the data.

A direct comparison of the services helps make the decision for the right appraisal easier. The standard appraisal for auf Anfrages is sufficient for the majority of car owners who are selling or having appraised a combustion engine or simple hybrid vehicle. The premium appraisal for auf Anfrages is specifically aimed at owners of pure electric cars or complex systems such as residential PV storage systems. The table below summarizes the key differences:

This structured approach ensures that customers do not pay for services that are not relevant to their specific vehicle. At the same time, it ensures that the necessary depth of inspection is maintained for technologically demanding assets.

A key factor influencing the cost of a value appraisal is logistics. Traditionally, a vehicle must be brought to an inspection center or workshop, which takes time and is often associated with waiting periods. DIAVAG takes a mobile approach: the appraiser comes to the asset's location. Whether in the home garage, at the dealer's lot, or at the harbor in the case of a boat, the inspection takes place wherever the vehicle is located. This service is already included in the fixed prices of auf Anfrages or auf Anfrages, provided the location is within one of the areas.

The time savings for the customer are considerable. An appointment can usually be arranged within 24 hours. On site, the standardized process for a car takes less than 15 minutes. Through the use of a mobile hardware case containing all the necessary calibrated measuring devices, no lift is required to produce a meaningful value appraisal. This efficiency allows DIAVAG to keep prices stable while ensuring high-quality documentation. Independence is the top priority: DIAVAG does not sell repairs or insurance, but delivers only neutral data.

A value appraisal is only worth as much as its legal recognition. In cases of inheritance, divorce or insurance claims, lawyers, notaries and courts require appraisals that meet certain standards. DIAVAG appraisers work according to the guidelines of the BVSK (Federal Association of Freelance and Independent Vehicle Appraisers). In addition, the system is designed to meet the requirements of ISO/IEC 17020 Type A, representing the highest level of independence as an inspection body. This means that the appraisals are usable in court and can serve as an objective basis for legal disputes.

In the case of legal questions, customers should always consult a lawyer or notary, as DIAVAG does not provide legal advice. However, the appraisal provides the necessary factual basis in accordance with the Judicial Remuneration and Compensation Act (JVEG), should it come to court use. A special security feature is the optional notarial hash on the Polygon blockchain. This digital fingerprint makes the PDF appraisal tamper-proof and proves beyond doubt that the data has not been altered since creation. This technological safeguard is included in the price and underscores the commitment to transparency and integrity.

The precision of a value appraisal depends significantly on the hardware used. Every DIAVAG appraiser carries a standardized hardware case with a list price of auf Anfrages. This case contains, among other things, an OBD2 scanner, a coating thickness gauge for paint inspection, a digital tread depth gauge for tires, and a digital multimeter for electrical measurements. These tools make it possible to objectively record the technical condition of a car without relying on subjective estimates.

The on-site workflow follows a strict protocol. First, the vehicle is identified via the vehicle identification number (VIN) in accordance with StVZO and FZV. Then the body is checked for accident damage and repaints. Technical diagnostics via the OBD2 interface provide information about hidden defects in the fault memory. For electric cars, the Premium Battery Test follows, which analyzes cell voltages and the health status of the battery. All data is fed into software in real time, which generates the appraisal. Final review and signing by a senior inspector ensures that every document meets high quality standards before being delivered to the customer as a PDF the same day.

While classic organizations such as TÜV or DEKRA focus primarily on cars and periodic technical inspections, DIAVAG covers a total of seven asset classes. This breadth is a unique selling point in the mobile appraisal market. In addition to cars and electric cars, boats (motor and sailing boats), construction and agricultural machinery (such as excavators or tractors), cargo bikes, e-scooters and even residential PV storage systems are appraised. Transparent fixed prices of auf Anfrages for standard assets and auf Anfrages for premium assets apply to each of these classes.

The mobile component is especially decisive for construction and agricultural machinery, since transporting these machines to an inspection center would be extremely costly. Here, the EU Machinery Regulation 2023/1230, which prescribes new safety standards from January 2027, also comes into play. DIAVAG appraisals already take these regulatory frameworks into account today. In the field of micromobility, i.e. cargo bikes and e-scooters, the need for professional value certificates is also growing, for example for insurance purposes or when reselling high-value e-cargo bikes. The uniform pricing structure across all classes creates trust and predictability for the customer.

For commercial customers such as car dealers or fleet operators, DIAVAG offers individual terms, provided a volume of at least 50 appraisals per month is reached. In this segment, it is not just about pure valuation, but about integration into existing processes. Via a DMS API (interface to Dealer Management Systems), appraisals can be fed directly into the dealer's software. This speeds up the purchasing process and ensures seamless documentation of the vehicle inventory.

Dealers benefit from the independence of the appraisal, as it serves as a neutral certificate towards end customers. This increases credibility and can shorten vehicle standing times. In addition, DIAVAG offers the hardware case including the software for purchase by self-employed appraisers (auf Anfrages). This enables partners to integrate the standardized DIAVAG workflow into their own portfolio. The combination of mobile on-site data collection and central review by senior inspectors guarantees consistently high quality, regardless of where in Germany the appraisal is created.

It is important to distinguish DIAVAG from other service providers in the automotive sector. DIAVAG is not an inspection organization like TÜV, which carries out periodic technical inspections (HU/AU). While TÜV checks road safety, DIAVAG determines the economic value and detailed technical condition of an asset. Similarly, DIAVAG differs from car purchase platforms. These portals often have a vested interest in purchasing the vehicle at the lowest possible price. DIAVAG, on the other hand, does not sell vehicles and thus has no interest in artificial devaluation.

The service also clearly differentiates itself from purely algorithmic valuation services, as found on large used car marketplaces. An algorithm cannot assess visual condition, odors in the interior, or actual paint thickness. A DIAVAG appraisal is based on a physical on-site inspection by a qualified appraiser. Only this combination of human expertise and calibrated measurement technology leads to a result that holds up before insurers or courts. Independence is the strongest argument here: since DIAVAG does not offer repairs, there is no incentive to invent or overlook defects.
