Get Your Vehicle Valued: Mobile Valuation Report for M&A and Due Diligence

The need to have a vehicle valued arises from various life situations. In M&A scenarios and when valuing business assets, subjective price expectations often clash with market reality. An independent report objectifies this negotiation. It documents the technical condition, equipment and any defects in black and white. This protects the seller from later recourse claims and gives the buyer confidence that they are paying a fair price.

Besides classic purchase and sale, legal occasions also play a central role. In business succession or as part of due diligence, the value of the vehicle inventory must be determined precisely to enable an accurate asset valuation. Here, appraisers refer to the Justizvergütungs- und Entschädigungsgesetz (JVEG, the German act on judicial compensation) as a reference framework to deliver results usable in court. Also in insurance cases, for example after a natural disaster or to determine the replacement value, a detailed valuation report is essential. DIAVAG ensures that these reports are prepared in compliance with BVSK standards, which increases their acceptance among authorities and insurers. However, for specific legal questions, you should always consult a lawyer or notary.

Many vehicle owners initially use free online calculators to get an initial indication of their car's value. However, these algorithms are based purely on statistical data such as year of manufacture, model and mileage. They cannot account for the individual maintenance condition, expensive special equipment or hidden defects. Such an estimate is therefore no substitute for a physical inspection by an expert.

Unlike pure purchasing platforms, which often offer low prices in order to resell the vehicle themselves, DIAVAG remains completely independent. We do not sell vehicles, do not sell insurance, and do not perform repairs. This independence is the fundamental prerequisite for a neutral report according to ISO/IEC 17020 Type A. While an online valuation merely provides a non-binding figure, an appraiser's report is a document of legal relevance. The appraiser checks details on site that no algorithm can capture, such as paint thickness to identify accident damage or the fault memory via OBD2 interface.

A key advantage of the DIAVAG model is mobility. Traditionally, vehicle owners had to make an appointment with an inspection body such as TÜV or DEKRA and transport the vehicle there. This is time-consuming and, for unregistered vehicles, involves considerable logistical effort. DIAVAG reverses this process: the appraiser comes to the asset, whether that is a garage, a dealer's lot, or a harbor.

This mobile service is particularly valuable for high-value assets or vehicles that cannot easily be moved, such as construction and agricultural machinery or boats. Within the regions of Hamburg, Berlin and Munich, we guarantee an appointment within 24 hours. The on-site inspection usually takes less than 15 minutes, as our appraisers follow a standardized and highly efficient workflow. Digital data capture allows the finished PDF report to be delivered the same day. This speed is a decisive factor when it comes to time-critical transactions or insurance deadlines.

The costs of a vehicle valuation report are often non-transparent and, with many providers, depend on the vehicle's value or the time required. DIAVAG breaks with this practice and offers clear fixed prices. For the private standard, which covers combustion-engine cars, boats, cargo bikes and e-scooters, we offer attractive fixed prices. This amount includes travel within the region, the on-site inspection, and preparation of the report.

For more complex valuations, particularly for electric vehicles, home storage systems or high-value assets, we charge a premium fixed price. This additional cost is justified by the use of specialized hardware, such as the Premium Battery Test, which enables an in-depth diagnosis of the high-voltage battery. For commercial customers, such as car dealers or fleet operators, we offer individual terms starting at a volume of 50 reports per month. This price stability gives customers planning certainty and prevents unpleasant surprises from subsequent fees or hourly billing.

For electric vehicles, the drive battery is the most expensive component, often accounting for up to 40 percent of the total value. Anyone wanting to have a used EV valued should therefore not rely solely on its visual condition. The State of Health (SoH) of the battery largely determines the vehicle's residual value. Conventional inspection bodies often only offer a basic diagnosis here, which says little about the actual capacity.

DIAVAG integrates the Premium Battery Test as standard into the premium report. Using calibrated hardware, our appraisers measure cell balance, kWh capacity, internal resistance, and analyze the charging curve. This data is essential for objectively assessing the remaining lifespan and performance of the storage unit. Since the EU Battery Passport becomes mandatory from February 2027, DIAVAG is already prepared today to meet these requirements. Buying or selling an EV without a detailed battery assessment poses a significant financial risk, which is minimized by our specialized diagnostics.

The quality of a report stands and falls with the qualification of its creator and adherence to recognized standards. All DIAVAG appraisers work according to the guidelines of the BVSK (Bundesverband der freiberuflichen und unabhängigen Sachverständigen für das Kraftfahrzeugwesen). This guarantees a high professional standard and adherence to ethical principles in report preparation. While AI speeds up data analysis, our experts control the conclusions; every document is finally reviewed and signed by a senior inspector before being sent to the customer as a PDF.

In addition, DIAVAG is designed as an inspection body according to ISO/IEC 17020 Type A, which represents the highest level of independence. This means we have no self-interest whatsoever in the disposal of the vehicle. This formal independence is especially important when reports are to be used in court, with insurers, or in official proceedings. Optionally, we offer the possibility of securing the report with a notarial hash on the Polygon blockchain. This creates tamper-proof evidence. Our processes are also certified to SOC 2 Type II and ISO 27001 to ensure the highest level of data security. In complex legal disputes, our report serves as a well-founded basis of evidence, although the final legal assessment must always be made by a lawyer.

The vehicle valuation process at DIAVAG follows a strict, digitally supported protocol. As soon as the appraiser arrives at the vehicle, standardized photo documentation begins. This captures not only the vehicle's best angles, but specifically all value-relevant areas as well as potential weak points. The next step involves using the OBD2 scanner to read the fault memory and capture real-time parameters from the control units.

A crucial tool in the appraiser's case is the paint thickness gauge. It can be used to precisely determine whether certain areas have been repainted, which is a reliable indicator of repaired accident damage, even if it has been visually perfectly disguised. Furthermore, tire tread depth is checked with a digital gauge and electrical systems with a multimeter. All collected data flows directly into our software. This technology-driven approach ensures full traceability, eliminates human transcription errors, and delivers consistently high-quality reports, regardless of whether the inspection takes place in Hamburg, Berlin or Munich. The calibrated hardware ensures that measurement results are precise and reproducible.

While many appraisal services specialize in cars, DIAVAG covers a total of seven asset classes. This makes us the ideal partner for customers with diverse inventories or special requirements. In addition to combustion vehicles and EVs, we value boats, construction and agricultural machinery, cargo bikes, e-scooters and even home storage systems for photovoltaic installations. Each of these classes requires specific expertise and adapted testing methods.

For boats, hull integrity and drive technology are the focus, while for construction and agricultural machinery, compliance with the EU Machinery Regulation and general wear under load are decisive. Home storage systems are checked analogously to EVs with a Premium Battery Test for capacity and cell balance. This breadth of portfolio is a unique selling point compared to classic inspection bodies such as TÜV, which generally do not offer specialized reports for boats or PV storage systems in the mobile sector. Whether it's valuing a fleet of cargo bikes or determining the value of a combine harvester for a business handover: DIAVAG delivers the appropriate standard at a fixed price.

For commercial customers, DIAVAG offers tailored solutions that go beyond individual reports. Dealerships and fleet managers often face the challenge of valuing a large number of vehicles in a short time, for example during lease returns or year-end inventory. Starting at a volume of 50 reports per month, we provide individual terms and enable seamless integration into existing Dealer Management Systems (DMS) via API connection.

Additionally, we offer our hardware case, including specialized software, for purchase to appraisal firms or dealers who want to conduct their own inspections. At attractive terms, professionals receive the complete equipment to implement the DIAVAG standard independently. This includes access to our platform for creating BVSK-compliant reports. By standardizing processes, fleet operators can precisely track the residual value of their vehicles and make informed decisions about the optimal time to sell. DIAVAG's independence ensures that the valuations remain objective and are not influenced by sales interests.
