Value Appraisals at a Fixed Price of auf Anfrages with DIAVAG

In the traditional appraisal industry, fees are often based on the determined vehicle value or billed according to time spent. For you as a customer, this leads to considerable uncertainty about the final cost. DIAVAG breaks with this practice and introduces a clear fixed-price model. The private standard rate for cars, boats, cargo bikes and e-scooters is auf Anfrages. This price is fixed and covers the entire mobile inspection as well as the creation of the appraisal. There are no hidden travel fees within the regions of Hamburg, Berlin and Munich.

The predictability of costs is especially important in legal disputes or estate administration. When a notary or lawyer needs to have several assets appraised, the fixed price offers a reliable basis for the cost breakdown. You already know exactly what amount will appear on the invoice before booking the appointment. This transparency fosters trust in the independence of the appraiser, since there is no financial incentive to artificially influence the vehicle value or unnecessarily prolong the inspection time. DIAVAG's model is designed to combine efficiency and legal certainty without compromising the quality of the technical inspection.

A key advantage of DIAVAG is mobility. The appraiser comes to the asset, whether that's a private garage, a dealer's yard, a harbor, or the location of a construction machine. This approach saves you valuable time and logistical effort. Especially for unregistered vehicles, seasonally used boats or heavy agricultural machinery, transport to a testing station is often associated with high costs and risks. DIAVAG solves this problem with a nationwide mobile service that enables appointments within 24 hours in the regions.

On site, the appraiser carries out a highly standardized workflow. Despite the short on-site duration of under 15 minutes, no component is overlooked. This is made possible by using a special hardware case containing all the necessary measuring instruments. Mobility doesn't end with travel to the site; it continues into digital processing. Since all data is captured digitally directly on site, subsequent manual entry in the office is eliminated. This massively speeds up the process, so you often receive the finished PDF appraisal the same day. A nationwide rollout is planned for 2026 to offer this standard across Germany.

The independence of an appraiser is the highest asset when it comes to the legal admissibility of an appraisal. As a brand of CITO GmbH, DIAVAG is strictly positioned as neutral. The company does not sell vehicles, does not broker insurance, and does not carry out repairs. This clear separation from trading and workshop interests distinguishes DIAVAG from many market participants such as car-buying portals or workshop-affiliated inspectors. A DIAVAG appraisal serves exclusively to objectively document the current condition and determine the market value.

This neutrality is especially decisive in divorces, inheritance matters or insurance cases. An appraisal that could be challenged by a party because its author has a vested interest in purchasing or repairing the asset loses weight in court or with insurers. DIAVAG meets the requirements of an inspection body under ISO/IEC 17020 Type A, representing the highest level of independence. Each appraisal is also finally checked and signed by a senior inspector. For complex legal questions, you should always consult a lawyer or notary, but DIAVAG provides the necessary, robust factual basis for their work.

Quality through standardization is the guiding principle of the DIAVAG inspection. Every appraiser uses the identical hardware setup to rule out subjective misinterpretations. A modern OBD2 scanner is used to read out the fault memory and capture real-time parameters of the onboard electronics. A coating thickness gauge checks the paint surface for repainting or hidden accident damage. This is supplemented by digital tread depth gauges and multimeters for testing electrical systems. This technical depth goes far beyond a purely visual assessment.

A key component is standardized photo documentation. Each asset is photographed according to a fixed scheme to capture all value-relevant areas completely. These images are tamper-proof and form the visual backbone of the appraisal. The combination of calibrated hardware and a digital checklist ensures that every appraisal - whether created in Hamburg, Berlin or Munich - meets the same high quality standard. This process is optimized to protect the customer's privacy and to minimally disrupt dealer operations. The result is a technical document that precisely and incorruptibly reflects the condition of the asset.

For electric vehicles and stationary home battery storage systems, the battery is the most valuable component. A simple value determination based on age and mileage falls short here. That's why DIAVAG has established the Premium Battery Test as the standard for these asset classes. For a fixed price of auf Anfrages, customers receive an in-depth diagnosis of the high-voltage battery. This measures the State of Health (SoH), cell balance, actual kWh capacity and internal resistance. This data is crucial for realistically assessing the residual value of an electric car.

Conventional testing organizations often only offer a basic diagnosis that merely reads superficial data from the battery management system. DIAVAG's Premium Battery Test goes deeper and already prepares the asset for the upcoming EU Battery Passport, which becomes mandatory from February 2027. This test is also essential for owners of PV home storage systems, for example in property transactions or in the event of warranty disputes with the manufacturer. Certified proof of the storage system's actual capacity protects against financial losses and creates clarity for buyers and sellers. DIAVAG positions itself here as a technical pioneer in a market increasingly dominated by electric storage systems.

While many appraisal services specialize in cars, DIAVAG covers a total of seven asset classes. These include not only combustion vehicles and electric cars but also boats, construction and agricultural machinery, cargo bikes, e-scooters and home storage systems. This breadth is a unique selling point in the German market. A boat owner in Hamburg can thus use the same professional service for their yacht as a construction company owner in Munich for their fleet of excavators and wheel loaders. Each class has a specific inspection catalog tailored to its respective technical requirements.

Especially in micromobility, such as high-value e-cargo bikes, demand for official value appraisals is growing. These assets often have purchase prices in the mid four-figure range, which requires precise value determination by insurers in the event of theft or accidents. DIAVAG also offers a fast and cost-efficient solution for the handover of family businesses in the agricultural sector, in order to legally appraise the machinery fleet. The combination of asset diversity and mobile fixed-price service makes DIAVAG a universal partner for private and commercial customers who value standardized and independent expertise.

To understand DIAVAG's positioning, it's worth comparing it with other market participants. Online estimation services are based purely on algorithms and statistical data. They do not take into account the individual technical condition or maintenance history on site. Such a document has little standing in court or with insurers. On the other hand, there are the large testing organizations, which do carry out physical inspections but often do not offer specialized battery diagnostics for electric cars and reach their limits with assets such as boats or home storage systems.

DIAVAG closes the gap between fast but imprecise online estimation and the expensive, often inflexible classic appraisal creation. Through specialization in mobile, technology-supported inspections, a level of detail is achieved that is essential for modern assets such as electric vehicles. Independence remains fully preserved, as DIAVAG has no interest in the vehicle's later transaction value.

In a digital world, the tamper-resistance of documents is of central importance. DIAVAG relies on state-of-the-art technologies here. Every appraisal created can optionally be provided with a notarial hash on the Polygon blockchain. This creates an unchangeable digital fingerprint of the document. Buyers or insurers can thus verify at any time that the PDF in front of them corresponds exactly to the original signed by the appraiser. This technology protects against fraud attempts through subsequent changes to values or condition descriptions.

Data is stored in compliance with GDPR on servers within the European Union. For commercial customers such as car dealers or fleet operators, DIAVAG also offers an API connection to existing Dealer Management Systems (DMS). Starting at a volume of 50 appraisals per month, individual terms can be agreed to further automate the inventory valuation process. DIAVAG also offers a solution for self-employed appraisers: the hardware case including specialized software can be purchased at a list price of auf Anfrages in order to integrate the DIAVAG standard into one's own portfolio. This underscores DIAVAG's ambition to be not just a service provider, but a technological enabler for the entire industry.
