Monday morning in an underground garage in Hamburg-Eppendorf. A Tesla Model 3 and a classic combustion-engine car are due for appraisal, as they need to be precisely valued as part of an inheritance settlement. The notary in charge needs solid figures that will hold up to legal scrutiny. In moments like this, the question of the cost of a valuation report is decisive. While traditional appraisal firms often bill using variable hourly rates and travel costs, DIAVAG relies on a model of absolute price transparency. The appraiser comes directly to the vehicle's location, carries out a standardized inspection, and delivers a legally sound document at a fixed price the same day.
Overview of the Pricing Structure for Valuation Reports
The cost of a valuation report depends largely on the type of object and the required scope of inspection. In the automotive appraisal industry, fees vary widely, as many firms bill based on the value of the object or by time spent. This often leaves you, as the customer, with a lack of predictability. DIAVAG has standardized this process to offer nationwide, consistent quality at fixed terms.
For standard assets such as combustion-engine cars, boats, cargo bikes, or e-scooters, the fixed price is auf Anfrages. This amount covers the entire process: from scheduling an appointment within 24 hours, to the mobile visit, to the creation of the BVSK-compliant PDF report. There are no hidden fees for travel within the regions of Hamburg, Berlin, and Munich. For more complex assets that require in-depth electronic diagnostics, a premium rate of auf Anfrages is charged. This applies in particular to electric vehicles and stationary home storage systems, where battery condition significantly influences market value.
The Standard Fixed Price of auf Anfrages for Cars and Boats
The standard report for auf Anfrages is aimed at owners of vehicles and maritime assets who need an independent valuation for a sale or insurance purposes. On site, the appraiser uses a specialized hardware kit containing calibrated measuring instruments. These include a coating-thickness gauge to identify repainting and accident damage, as well as a tread-depth gauge for the tires.
This fixed price also applies in the maritime sector, for example for sport or sailing boats. Here, the hull condition, propulsion technology, and general condition are assessed. Because DIAVAG operates independently and does not sell vehicles or repairs, the result is objective and credible for third parties, such as buyers or insurers. Documentation is carried out via a standardized photo set that records the condition in a tamper-proof manner. The finished report is signed by a senior inspector, which ensures quality and compliance with BVSK guidelines.
Premium Reports for EVs and the Premium Battery Test
For electric vehicles, the traction battery is the most valuable component. A superficial inspection is not enough here to determine a fair market value. That's why the premium report for EVs costs auf Anfrages. This price includes the so-called Premium Battery Test. This test goes far beyond simply reading out onboard computer values, as is often the case with conventional inspection organizations.
The appraiser analyzes the state of health (SoH), the cell balance, and the actual kWh capacity of the high-voltage battery. This data is essential, since a battery with 85 percent remaining capacity results in a noticeably lower vehicle value than a like-new storage unit. With the upcoming EU Battery Passport, which becomes mandatory from February 2027, DIAVAG already offers documentation today that meets these requirements. For buyers of a used EV, this report provides the necessary certainty against costly bad purchases.
Valuation of Home Storage Systems and Photovoltaic Installations
A growing area in valuation is stationary home storage systems for photovoltaic installations. When a property is sold or inherited, the value of the technical systems must be precisely determined. Here too, the premium fixed price of auf Anfrages applies. The appraiser checks the capacity and technical condition on site of storage systems from well-known manufacturers such as BYD, Sonnen, or Tesla.
Since these systems are often the subject of warranty disputes, an independent report under ISO/IEC 17020 Type A is highly valuable. It serves as an objective basis for negotiations with installers or manufacturers. The mobile inspection takes place directly in the utility connection room or at the storage unit's installation site. Using digital multimeters and specific diagnostic software, a detailed picture of cell health is created that goes far beyond the readings of conventional monitoring apps.
Legal Certainty Through BVSK and ISO 17020 Type A
A valuation report is only as valuable as its acceptance by third parties. DIAVAG appraisers are qualified according to BVSK standards. The service is also designed as an inspection body under ISO/IEC 17020 Type A, representing the highest level of independence. This means there are no economic ties whatsoever to workshops, car dealerships, or insurers.
In legal contexts such as inheritance, divorce, or insurance cases, this independence is crucial. The report can serve as the basis for valuation according to JVEG when used in court disputes. Optionally, DIAVAG offers the option of securing the report using a notarial hash on the Polygon blockchain. This makes the document tamper-proof and provides unequivocal evidence of the time of creation and its content. However, for specific legal questions, you should always consult a qualified lawyer or notary, as the appraiser may not provide legal advice.
Comparison of Services: DIAVAG vs. Competitors
To put the cost of a valuation report into perspective, it's worth comparing it with other market participants. While inspection organizations such as TÜV or DEKRA focus on periodic technical inspections, DIAVAG specializes in mobile valuation. Pure online estimation services, on the other hand, dispense entirely with a physical inspection, which significantly limits accuracy and legal usability.
| Feature | DIAVAG | Inspection organizations | Online estimators |
|---|---|---|---|
| Price | auf Anfrage / auf Anfrage fixed price | Often based on effort | Free to low-cost |
| Mobile service | Yes, on-site at the asset | Mostly stationary | None |
| Battery diagnostics | Premium Battery Test (SoH) | Basic diagnostics | None |
| Legal certainty | BVSK / ISO 17020 Type A | High (HU focus) | Low |
| Asset classes | 7 classes (incl. boat/storage) | Focus on cars/trucks | Cars only |
B2B Terms for Dealers and Fleet Operators
For commercial customers such as car dealerships, leasing companies, or fleet operators, DIAVAG offers scalable solutions. From a volume of 50 reports per month, individual terms are agreed that are tailored to the specific needs of the company. A major advantage for dealers is the API connection to existing dealer management systems (DMS). This enables a seamless workflow from trade-in to digital vehicle file.
Speed is a critical factor here. Since the appraiser arrives on site within 24 hours and the inspection takes less than 15 minutes, vehicle downtime is minimized. The PDF report is available the same day, speeding up the resale process. For independent appraisers looking to boost their own efficiency, DIAVAG also offers the hardware kit including the specialized software at a list price of auf Anfrages.
Construction and Agricultural Machinery: Valuation for Professionals
Appraising heavy machinery such as excavators, wheel loaders, or tractors requires special expertise and robust documentation. DIAVAG covers this asset class nationwide. Especially during the handover of family businesses or in the case of insurance claims, a precise residual-value report is essential. The appraiser checks not only the visual condition but also the operating hours and the functionality of the hydraulic systems.
In view of the EU Machinery Regulation 2023/1230, which becomes mandatory from January 2027, technical documentation is gaining importance. A professional valuation report helps to transparently track the depreciation over the years and provides a solid basis for resale or accounting. Here too, the promise of fast processing applies: the appointment takes place at short notice at the yard or construction site, disrupting ongoing operations as little as possible.
