Mobile Appraiser On-Site Fast: Independent Value Appraisals

Commissioning a mobile appraiser marks a paradigm shift in vehicle and asset appraisal. Traditionally, owners had to bring their vehicles to stationary inspection facilities such as TÜV or DEKRA. This is associated with considerable time expenditure, appointment lead times and often also transfer costs. A mobile appraiser from DIAVAG, on the other hand, comes directly to the asset. Whether in a private garage in Berlin-Charlottenburg, at a berth in Hamburg harbor, or on a farm near Munich - the inspection takes place wherever the object is located.

This service is particularly valuable for assets that cannot easily be moved, such as home storage systems, boats or heavy construction machinery. DIAVAG guarantees an appointment within 24 hours of the request. On site, the standardized inspection process usually takes less than 15 minutes. Through the use of calibrated hardware and a specialized software solution, all data is captured in real time. This significantly reduces the error rate and increases efficiency compared to manual, paper-based processes. The customer receives the final, legally sound PDF appraisal on the same day, which is especially decisive for time-critical transactions such as a private sale or an insurance settlement.

While classic inspection organizations primarily focus on passenger cars, DIAVAG covers a total of seven asset classes. This breadth is a key differentiator in the market for independent appraisers. The first class comprises classic cars with combustion or hybrid drivetrains. Here, general condition, accident-free history and market value are the main focus. The second class consists of electric vehicles, where the condition of the high-voltage battery is the value-determining element. This is where the Premium Battery Test comes in, to precisely determine the state-of-health (SoH).

In addition, DIAVAG appraises boats and yachts, which is particularly relevant for insurance policies or seasonal purchases. The fourth class comprises construction and agricultural machinery, where technical operational readiness and residual value are important for companies' balance sheets. Micromobility assets such as cargo bikes and e-scooters form the fifth and sixth classes. These are gaining massive importance in urban areas but are often neglected by conventional appraisers. The seventh class is PV home storage systems. Here DIAVAG offers a specialized assessment that serves as an objective basis in real estate transactions or in the event of warranty disputes with the manufacturer. For each of these classes, the appraiser uses specific inspection protocols to guarantee a market-appropriate valuation.

The quality of an appraisal stands and falls with the precision of the on-site data collection. Every DIAVAG appraiser carries a standardized hardware case with them, the contents of which represent a market value of around auf Anfrage. The core of the examination is the OBD2 scanner, which delves deep into the onboard electronics and reads out fault memory as well as real-time parameters. A digital paint thickness gauge is used to assess the bodywork. This allows repainting and hidden accident damage, which would remain invisible to the naked eye, to be identified beyond doubt.

A tread depth gauge documents the condition of the tires, while a digital multimeter is used to test electrical systems. Special attention is paid to standardized photo documentation. The appraiser follows a fixed workflow to record all value-relevant details in a tamper-proof manner. For electric vehicles and home storage systems, the Premium Battery Test is additionally carried out. This test analyzes the cell balance, the charging curve and the internal resistance of the battery. The result is a well-founded statement about the actual capacity compared to the new condition. All collected data flows directly into DIAVAG's cloud platform, where it is reviewed and finally signed off by a senior inspector. This multi-stage process ensures that every appraisal meets the highest quality standards.

A decisive factor for the legal usability of an appraisal is the independence of its author. DIAVAG acts as a neutral instance and pursues no vested interests in the purchase or sale of vehicles. Unlike car-buying platforms, which often offer free appraisals in order to subsequently buy the vehicle at a low price, DIAVAG delivers an objective value appraisal for a fixed fee. The company does not sell insurance and does not carry out repairs. This strict separation of appraisal and trading is the basis for the trust of courts, insurers and notaries.

The qualification of the appraisers follows the guidelines of the BVSK (German Federal Association of Freelance and Independent Vehicle Appraisers). In addition, the structure is designed as an inspection body according to ISO/IEC 17020 Type A, which represents the highest level of independence in the inspection industry. For customers, this means that the appraisals form a solid basis in legal disputes, such as divorce, inheritance, or after a no-fault accident. If required, the appraisal can additionally be provided with a notarial hash on the Polygon blockchain. This digital fingerprint guarantees that the document has not been altered after creation, thus offering maximum protection against manipulation.

In the appraisal industry, billing by the hour or as a percentage of the vehicle's value is widespread. This often results in a lack of cost predictability for the customer. DIAVAG relies on a transparent flat-rate model here. For standard assets such as cars, boats, cargo bikes or e-scooters, the price for a private appraisal is auf Anfrage. This price includes travel within the regions of Hamburg, Berlin and Munich, as well as complete documentation and creation of the PDF appraisal.

For more complex assets that require in-depth battery diagnostics, the premium rate of auf Anfrage is charged. This applies to electric vehicles and home storage systems, as the Premium Battery Test is carried out here as an integral part of the valuation. This rate also applies to high-value assets in other categories. There are no hidden fees for travel or the provision of digital documents. For commercial customers, such as car dealers or fleet operators, who reach a volume of more than 50 appraisals per month, DIAVAG offers individual terms. These also include connection to existing Dealer Management Systems (DMS) via API, to further automate processes at the dealership. This price stability builds trust and allows both private individuals and companies to precisely plan the costs of a professional appraisal.

The value of a used electric vehicle is largely determined by the condition of the traction battery. Since the battery is the most expensive component of the vehicle, a simple visual inspection or reading out the onboard computer is not sufficient to make a credible value statement. This is where DIAVAG's Premium Battery Test comes in. While conventional inspection organizations often only offer basic diagnostics, DIAVAG delivers a detailed analysis of the state-of-health (SoH). Parameters such as cell voltage variance and internal resistance under load are measured.

This data is decisive not only for the current resale value, but also with regard to the upcoming EU Battery Passport, which will become mandatory for all new batteries in the EU from February 2027. DIAVAG is already prepared for these regulatory requirements today. A positive battery finding can stabilize or even increase the sale price of an EV, as it relieves the buyer's fear of a costly battery defect. This diagnostics is also essential for home storage systems. When a house with a photovoltaic system and storage is sold, the value of the storage system must be objectively determined. The mobile appraiser carries out the test on site, without the storage system needing to be dismantled. This offers a level of certainty that purely algorithmic estimates can never achieve.

There are numerous life situations in which a legally sound value appraisal is essential. In inheritance matters, the value of vehicles or machines must be precisely determined to enable a fair division among heirs or to correctly calculate inheritance tax. The same applies to divorce proceedings, where shared assets must be valued. In such cases, the independence of the appraiser is of the utmost importance in order to avoid accusations of bias. DIAVAG provides BVSK-compliant appraisals that meet the requirements for an objective valuation.

The appraisal also plays a central role in insurance claims. After a loss, the replacement value must be precisely determined so that the injured party is adequately compensated. A mobile appraisal directly after the event secures evidence and documents the condition of the asset promptly. However, it is important to emphasize that DIAVAG does not provide legal advice. For specific legal questions regarding inheritance law, family law or claims settlement, customers should always consult a qualified lawyer or notary. DIAVAG's appraisal serves as the technical and economic factual basis on which the legal assessment can be built. Compliance with the JVEG (Judicial Remuneration and Compensation Act) as a reference framework ensures high acceptance of the appraisals in legal contexts.

For professional players in the automotive trade and fleet management, DIAVAG offers specialized B2B solutions. Efficient inventory management requires fast and precise appraisals when purchasing or taking back leased vehicles. Through the mobile availability of the appraisers, dealers can reduce standing times, as vehicles do not need to be moved for an appraisal. From a volume of 50 appraisals per month, DIAVAG provides individual terms tailored to the specific needs of large customers.

A key technological advantage is the DMS API. This interface allows appraisal data to be transferred directly into the dealer's Dealer Management System. This eliminates manual data entry, which increases process speed and minimizes sources of error. For appraisers who want to become self-employed or expand their portfolio, DIAVAG also offers the hardware case including specialized software at a purchase price of auf Anfrage. This gives partners access to the standardized workflow and the DIAVAG brand. This enables a fast market entry with proven technology. Whether for the appraisal of a small fleet of e-cargo bikes or the nationwide inventory of a large dealership - the scalability of the system makes DIAVAG a strong partner for the commercial economy.
