Vehicle Appraiser Comes to Me: Mobile Service at a Fixed Price

Commissioning an appraiser who comes to the vehicle's location offers significant logistical advantages. Traditional inspection organizations often require that the vehicle be brought to a stationary inspection center. For deregistered vehicles, classic cars, or assets with technical defects, this is associated with high costs for transit license plates or towing services. A mobile appraiser eliminates these hurdles entirely. The appraiser fits into the customer's schedule, not the other way around.

In the areas of Hamburg, Berlin, and Munich, DIAVAG guarantees an appointment within 24 hours. The inspection on site usually takes less than 15 minutes, as the workflow is improved through digital checklists and calibrated hardware. This is especially important for working professionals or companies with vehicle fleets who don't want to risk downtime for their vehicles. The appraiser's independence is maintained, as the assessment follows strict BVSK standards and is finally signed off by a senior inspector (human-in-the-loop). The customer receives the legally sound PDF report the same day, which massively speeds up sales processes or insurance claims.

A common problem when commissioning appraisers is unclear fee billing, calculated on an hourly basis or based on the determined vehicle value. DIAVAG relies here on a transparent fixed-price model. For standard assets such as combustion-engine cars, boats, cargo bikes, or e-scooters, billing is at a fixed price. This amount includes travel within the areas as well as the creation of the report. There are no hidden fees for documentation or delivery of the digital report.

For more complex assets such as electric vehicles or home storage systems, a specialized premium rate applies. This surcharge is justified by the use of specialized diagnostic technology, particularly the Premium Battery Test. While conventional appraisers often only assess visual condition, DIAVAG delivers an in-depth analysis of the high-voltage battery for EVs. For commercial customers, car dealers, or fleet operators reaching a volume of more than 50 reports per month, individual terms are agreed. This price stability creates planning security for all parties involved, whether for complex M&A transactions or the portfolio valuation of a commercial fleet.

The quality of a mobile report depends significantly on the hardware used. Every DIAVAG appraiser carries a standardized hardware case calibrated for various asset classes. Standard equipment includes an OBD2 scanner that reads out the fault memory and the vehicle's real-time parameters. A paint layer thickness gauge is used to precisely identify repaints or hidden accident damage. These measurements are essential to objectively prove a vehicle's accident-free status.

Additionally, tread depth gauges for tires and digital multimeters for checking electrical systems are used. The entire inspection process follows a firmly defined protocol that includes complete photo documentation. These photos are stored tamper-proof and offer full source traceability within the report. This high degree of standardization ensures that every report has the same high quality, regardless of whether the inspection takes place in Berlin or Munich. Data is stored in a GDPR-compliant manner on servers within the European Union, guaranteeing the security of sensitive vehicle and customer data.

A decisive factor for the acceptance of a report by insurers, banks, or courts is the appraiser's independence. DIAVAG acts as a neutral authority and is not involved in vehicle sales, repair services, or insurance brokerage. This strict separation of interests is the prerequisite for classification as an inspection body under ISO/IEC 17020 Type A. This represents the highest level of independence and distinguishes the service from platforms that use reports merely as a means to an end for vehicle purchasing.

The appraisers' qualifications comply with the guidelines of the BVSK (Federal Association of Independent Motor Vehicle Appraisers). Each PDF report created is reviewed and signed by a senior inspector (human-in-the-loop). This ensures legal admissibility in contexts such as M&A transactions, portfolio valuations, or the settlement of insurance claims. If additional security is desired, DIAVAG optionally offers a notary hash on the Polygon blockchain. This digital fingerprint makes the document tamper-proof and proves the asset's condition at an exact point in time. For specific legal questions, however, customers should always consult a lawyer or notary, as the appraiser is not permitted to provide legal advice.

For electric vehicles, the traction battery represents the most valuable component, whose condition (State of Health, SoH) significantly influences market value. A simple look at mileage is not sufficient here. DIAVAG therefore integrates the Premium Battery Test as standard into the premium report. This test goes far beyond the basic diagnostics often offered by conventional inspection organizations. It determines the actual remaining capacity in kilowatt-hours, analyzes cell balance, and evaluates the charging curve as well as the battery's internal resistance.

This data is not only decisive for buying or selling a used EV but also for preparing for the EU Battery Passport, which becomes mandatory from February 2027. DIAVAG also offers this specialized diagnostics for stationary home storage systems used in conjunction with photovoltaic installations. In real estate transactions or warranty disputes, the report provides an objective data basis on the wear condition of the storage system. Without such technical testing, the value of an electrified asset remains pure speculation, which poses a significant financial risk for buyers and sellers.

While most mobile appraisers specialize in passenger cars, DIAVAG covers a total of seven asset classes. These include, in addition to cars and EVs, boats, construction and agricultural machinery, cargo bikes, e-scooters, and home storage systems. This breadth is unique in the market and allows customers to have various assets assessed through a single provider. A construction contractor, for example, can have his excavator fleet assessed, while asset managers prepare portfolios for exit.

Each asset class requires specific expertise and adapted testing methods. For construction machinery, operating hours and hydraulic systems are the focus, for example, while for boats hull substance and propulsion technology are decisive. The mobile service comes into play here, since transporting an excavator or a yacht to an inspection center is often impossible or extremely costly. DIAVAG brings the expertise directly to the harbor or the construction site. The reports also follow the strict requirements of the JVEG here, making them particularly valuable for assessing business assets or in insurance cases.

For commercial players such as dealerships, leasing companies, or fleet managers, time is a critical competitive factor. DIAVAG offers specialized B2B solutions for this target group. From a volume of 50 reports per month, individual terms can be agreed. A key advantage is API integration with existing Dealer Management Systems (DMS). This enables a seamless data flow and automates the creation of portfolio valuations or purchase offers.

The mobile appraiser can inspect entire vehicle fleets directly at the logistics site, minimizing vehicle downtime. Standardized documentation ensures objective comparability of the assets within the fleet. DIAVAG also offers the hardware case including the software solution at attractive terms for independent appraisers who want to expand their service portfolio. This supports the nationwide rollout planned for 2026 and ensures that commercial customers across Germany can access the same high quality standard.

The path to a finished value report at DIAVAG is designed for maximum efficiency. After commissioning, the appointment is scheduled within 24 hours. The appraiser arrives at the agreed location and carries out the technical inspection. All relevant data is captured digitally and documented with photos. The customer does not need to be present during the inspection, provided access to the asset is ensured. Once the on-site work is complete, the data is transmitted to headquarters, where a senior inspector (human-in-the-loop) checks plausibility and finalizes the report.

The result is a BVSK-compliant PDF document that is delivered to the customer by email the same day. This process eliminates the usual waiting times of several days or weeks that are often the norm at traditional appraisal firms. The combination of mobile flexibility, technical depth through the Premium Battery Test, and legal certainty through ISO certifications makes this service a modern solution for the valuation of mobile and stationary assets.
