Find an Independent Vehicle Appraiser Near You

Choosing an appraiser should primarily depend on their independence. An independent vehicle appraiser is defined by having no economic interest whatsoever in a subsequent repair, vehicle purchase, or the sale of insurance. DIAVAG operates as a pure inspection body under ISO/IEC 17020 Type A. This standard represents the highest level of independence. Unlike workshops or platforms that buy vehicles directly, a DIAVAG appraiser's judgment remains objective and neutral.

This neutrality is especially critical in legal disputes, inheritance cases, or divorces. If a report is to hold up in court or before the tax authorities, the qualification of its author must be beyond doubt. All DIAVAG appraisers work according to the guidelines of the BVSK (German Federal Association of Independent and Freelance Motor Vehicle Experts). A report signed by a senior inspector provides the necessary assurance for all parties involved. For specific legal questions, customers should always consult a lawyer or notary to clarify usability in individual cases.

The classic route to an appraiser usually involves scheduling an appointment at an inspection center or workshop. This requires time, organization, and often a second driver or a rental car. DIAVAG breaks this pattern. The appraiser comes to you, whether that's your home garage, a company yard, or the harbor. The service currently covers the regions of Hamburg, Berlin, and Munich. A nationwide rollout is planned for 2026.

Within these regions, no additional travel fees apply. An appointment is usually available within 24 hours. The efficiency of the process is evident on site: the standardized inspection typically takes less than 15 minutes. Thanks to mobile hardware cases, appraisers work independently and require no lift or external power supply. This makes the service ideal for vehicles that are not roadworthy or whose transport would be costly, such as construction and agricultural machinery or boats.

Quality in vehicle appraisal comes from standardization. Every DIAVAG appraiser uses an identical hardware set to rule out subjective misjudgments. An OBD2 scanner is used to read in-depth data from the fault memory and real-time vehicle parameters. A paint thickness gauge checks the paint surface for repainting or hidden accident damage. This is complemented by digital tread depth gauges and multimeters for testing electrical systems.

The standardized photo set is at the core of the documentation. Every image is taken according to a fixed scheme to guarantee complete visual evidence. Optionally, the report can be secured with a notarial hash on the Polygon blockchain. This makes the document tamper-proof and verifies the exact condition at the time of inspection. Data is stored in compliance with GDPR on servers within the European Union. The result is a BVSK-compliant PDF report with complete source traceability, where every finding is directly linked to the recorded image data and measurements.

Transparency begins with the price. Many appraisal firms bill by hourly effort or based on the determined vehicle value, which makes costs for the customer hard to predict. DIAVAG relies on a clear flat-rate model. DIAVAG offers standard value appraisals for cars, boats, cargo bikes, or e-scooters at a fixed price. This price includes travel within the region, the on-site technical inspection, and the creation of the digital report.

For more complex assets such as electric cars or home storage systems, specific flat-rate terms apply. This surcharge is justified by the included Premium Battery Test, which provides a detailed analysis of the high-voltage battery. For commercial customers, car dealers, or fleet operators with a volume of 50 or more appraisals per month, individual terms are agreed upon. DIAVAG also offers an API connection to common Dealer Management Systems (DMS), seamlessly integrating the appraisals into the dealer's digital processes. Independent appraisers also have the option to purchase the complete hardware case including software.

The market value of a used electric car depends largely on the condition of the battery. Conventional inspection organizations often only offer a basic diagnostic that is insufficient for a well-founded valuation. DIAVAG integrates the Premium Battery Test as standard in every EV appraisal. This measures the State-of-Health (SoH), cell balance, actual kWh capacity, and internal resistance. This data is crucial for objectively assessing the remaining capacity of the battery compared to its original condition.

With a view to the EU Battery Passport, which becomes mandatory from February 2027, DIAVAG is already technically prepared today. A detailed battery report protects buyers from expensive bad purchases and enables sellers to achieve a fair price for a well-maintained vehicle. Since the battery can account for up to 50 percent of an electric vehicle's total value, this specialized diagnostic is essential for a legally sound valuation. This technology is also used for residential PV storage systems, providing clarity on storage condition in property transactions or warranty disputes.

While most appraisers focus on cars, DIAVAG covers a total of seven asset classes. In addition to conventional and hybrid vehicles, the portfolio includes electric cars, boats, construction and agricultural machinery, cargo bikes, e-scooters, and home storage systems. This breadth is a unique selling point in the market. A farmer can therefore have their combine harvester appraised on the same day as their private car or the PV storage system on the barn roof.

Each asset class follows a specific inspection protocol. For boats, for example, the hull condition and drive technology are the focus, while for construction machinery, compliance with EU Machinery Regulation 2023/1230 and the general wear level of the hydraulic components are checked. Mobile availability is the decisive factor here, since transporting heavy machinery or boats to an inspection center would often be uneconomical. DIAVAG brings its expertise directly to the location of the equipment.

A value appraisal often serves as evidence in legal or insurance contexts. In an inheritance case, the value of the estate must be precisely determined for the tax office in order to correctly assess inheritance tax. In divorce proceedings, the market value of vehicles or machinery forms the basis for the equalization of accrued gains. In such cases, a simple online estimation tool is not sufficient, as it does not take into account the individual condition of the object.

The DIAVAG report is based on the German Judicial Remuneration and Compensation Act (JVEG) and thus provides a solid basis for legal disputes. Being signed by a senior inspector and complying with BVSK standards ensures high acceptance among authorities and insurers. In the case of a liability claim, the report also helps determine the replacement value. The final decision on recognition by the respective insurer or competent court rests with them. DIAVAG does not provide legal advice.

For professional players in the automotive trade, speed is a critical success factor. DIAVAG offers dealers and fleet operators a highly efficient system for inventory valuation and purchase inspection. From a volume of 50 appraisals per month, partners benefit from individual terms and deep integration into their existing IT infrastructure. Via a DMS API, appraisals are automatically transferred into the Dealer Management System, minimizing manual effort.

DIAVAG offers a partner model for independent appraisers. Partners can purchase the standardized hardware case including the specialized software. This allows smaller firms to offer their customers state-of-the-art diagnostics such as the Premium Battery Test without having to bear their own development costs. By connecting to the DIAVAG network, consistently high report quality is ensured, establishing the brand nationwide as synonymous with independent and mobile expertise.
