Getting a Neutral Value Appraisal for Your Car: Costs and Process

The neutrality of an appraiser is the foundation for the legal usability of an appraisal. Unlike many market participants who buy vehicles or broker insurance services, DIAVAG acts as a fully independent authority. We sell no vehicles, no insurance, and perform no repairs. This independence is certifiable under ISO/IEC 17020 Type A and guarantees that the determined value is based exclusively on technical facts and the current market situation.

A neutral value appraisal is especially indispensable when conflicting interests meet. This regularly occurs in cases of inheritance, divorce, or the settlement of insurance claims. While algorithm-based estimates often provide only average values, a physical appraisal takes into account individual condition, maintenance history, and specific equipment features. The qualification of our appraisers according to BVSK standards ensures that the appraisals also hold up before authorities and in legal contexts.

The process at DIAVAG is designed for maximum efficiency and precision. After booking, the appointment usually takes place within 24 hours. The appraiser comes directly to the asset's location, whether it's a private garage, a farmyard, or a harbor. On site, a standardized inspection workflow is carried out, ensuring complete documentation. The physical inspection usually takes less than 15 minutes, minimizing inconvenience for the customer.

State-of-the-art hardware from the DIAVAG system case is used for this. A paint layer thickness gauge checks the paintwork for repainting or hidden accident damage. The OBD2 scanner reads the fault memory and relevant real-time parameters. In addition, tread depths are measured and standardized photo documentation is created. This data is processed in real time and finally reviewed and signed by a senior inspector. The completed PDF appraisal is delivered the very same day.

Transparency starts with pricing. DIAVAG deliberately avoids complicated hourly billing or hidden travel fees within the regions of Hamburg, Berlin, and Munich. Clear flat prices apply for private customers, providing planning certainty. A standard value appraisal for cars, boats, cargo bikes, or e-scooters costs auf Anfrage. This price covers the entire mobile inspection and the creation of the BVSK-compliant appraisal.

For technologically more complex assets such as electric cars or home storage systems, the flat price is auf Anfrage. This premium package includes the Premium Battery Test, which provides a detailed analysis of the state of health (SoH). For commercial customers, dealers, or fleet operators with a volume of 50 or more appraisals per month, we offer individual terms. These also include API integration with existing dealer management systems (DMS) to seamlessly integrate the valuation processes into the company's digital infrastructure.

An appraisal is only as valuable as its acceptance by third parties. DIAVAG relies on the highest standards to ensure the court-usable quality of the documents. All our appraisers work according to the guidelines of the BVSK (German Federal Association of Freelance and Independent Motor Vehicle Appraisers). In addition, the system is designed as an inspection body under ISO/IEC 17020 Type A, which represents the highest level of independence in the testing sector.

For legal disputes, such as valuation under the Judicial Remuneration and Compensation Act (JVEG), DIAVAG offers a solid foundation. Optionally, the appraisal can be provided with a notarial hash on the Polygon blockchain. This creates tamper-proof evidence of the condition and value at the time of inspection. For complex legal questions arising from inheritance or divorce, we always recommend consulting a lawyer or notary to correctly use the appraisal's findings legally.

For electric vehicles, the drive battery is the value-determining component, which can account for up to 50 percent of the total value. A conventional appraisal that only assesses visual condition falls short here. DIAVAG therefore integrates the Premium Battery Test as standard in every EV appraisal. This precisely measures the state of health (SoH), cell balance, actual kWh capacity, and internal resistance.

This test goes far beyond the basic diagnostics often offered by conventional testing organizations. Since DIAVAG is already prepared for the upcoming EU Battery Passport (mandatory from February 2027), customers receive a future-proof valuation. A high SoH value is a decisive selling point and protects buyers from unpredictable follow-up costs due to a weakening battery. Data is stored GDPR-compliant on servers within the EU.

There are various ways to determine the value of a vehicle. The following table illustrates the differences between DIAVAG and other market participants:

A key unique selling point of DIAVAG is the breadth of covered asset classes. While classic appraisal offices are often specialized in motor vehicles, we value a total of seven categories. In addition to cars and EVs, this includes sport and sailing boats, construction and agricultural machinery, as well as micromobility solutions such as cargo bikes and e-scooters. Even stationary home storage systems for photovoltaic installations are examined by our experts.

A specific yet equally standardized workflow is used for each of these classes. For construction machinery, for example, the focus is on the EU Machinery Regulation and residual value logic for commercial redeployment. For boats, the drive systems are assessed in addition to the hull condition. This versatility makes DIAVAG the ideal partner for estate administrators or companies with mixed fleets seeking a central solution for all valuation questions.

For lawyers, notaries, and insurance claims handlers, DIAVAG offers procedural relief. The speed from commissioning to the completed appraisal enables swift handling of mandates and claims. Because our appraisals are BVSK-compliant and signed by senior inspectors, they meet the requirements for professional evidence preservation. This is especially relevant for handling lease returns or valuing business assets.

Dealers and fleet operators also benefit from scalability. From a volume of 50 appraisals per month, we not only provide individual terms but also enable integration of our data into existing IT systems. This allows precise residual value tracking and optimizes the purchasing process. Independent appraisers also have the option of purchasing the DIAVAG hardware case, including the software, for auf Anfrage, to take their own services to the next digital level.

To ensure a smooth inspection in under 15 minutes, some preparations should be made. Make sure the vehicle or asset is freely accessible and that there is enough space for complete all-around documentation. The vehicle should ideally be cleaned so that paint condition and any damage can be clearly identified. Keep all relevant documents ready, such as the vehicle registration document parts I and II, the service booklet, and invoices for recent repairs or investments.

For electric cars and home storage systems, it is important that the system is operational so that the Premium Battery Test can be carried out. The appraiser needs access to the OBD2 interface or the storage system's connection points. Through this preparation, you support the precision of the appraisal and help ensure that the determined market value correctly reflects all value-increasing factors. After the on-site inspection is complete, there is nothing else for you to do - the appraisal is delivered to you automatically.
