Find an Appraiser Nearby: Mobile Service at a Fixed Price

The classic search for an appraiser nearby usually ends at a stationary inspection center or a workshop. For the vehicle owner, this means considerable logistical effort. Appointments must be coordinated, travel times planned, and waiting times on site accepted. Especially for vehicles that are not roadworthy, seasonally registered boats, or stationary home storage systems, transport to an inspection center is often impossible or comes with high costs.

DIAVAG solves this problem with a consistently mobile concept. The appraiser comes to the asset, whether it is located in a garage, on a yard, in a harbor, or in a machinery park. In the regions Hamburg, Berlin and Munich, appointments are scheduled within 24 hours. This time advantage speeds up sales decisions and urgent insurance matters. The on-site inspection typically takes less than 15 minutes, as the workflow has been improved through digital support and standardized hardware kits. The customer saves valuable time, while the quality of the assessment remains at the highest level through the use of calibrated technology.

Another aspect of the mobile service is stress reduction in legal disputes. In cases of inheritance or divorce, the assets are often located at different sites. A mobile service provider can visit them one after another and create a uniform basis for valuation. This is a structural advantage over local appraisal offices, which often only cover a limited radius or charge high travel fees. At DIAVAG, travel costs within the regions are included in the fixed price, ensuring maximum cost transparency.

While conventional inspection organizations such as TÜV or DEKRA focus almost exclusively on motor vehicles, DIAVAG covers a total of seven asset classes. This breadth is rare in the market of independent appraisers. In addition to classic combustion-engine cars, the portfolio includes EVs, boats, construction and agricultural machinery, cargo bikes, eScooters, and even PV home storage systems. Each of these classes requires specific expertise and adapted testing methods.

For boats and yachts, for example, the appraisal often takes place directly at the harbor or in winter storage. Here, it's not just about the visual condition, but also the technical integrity of the hull and propulsion systems. For construction and agricultural machinery, on the other hand, functional safety and residual economic value are the focus. This is where the EU Machinery Regulation 2023/1230 applies, among other things, compliance with which is essential for commercial users. An appraiser nearby who understands these special classes is equally valuable for businesses and private individuals.

Particularly innovative is the appraisal of home storage systems and micromobility solutions such as cargo bikes. Since these assets are increasingly part of real estate transactions or corporate fleets, the need for legally sound proof of value is growing. A standardized appraisal report from DIAVAG provides the necessary security here for buyers and sellers. Through uniform documentation and signing by a senior inspector, it is ensured that every appraisal report meets the high requirements of the BVSK, regardless of the asset in question.

Unpredictable costs often complicate hiring an appraiser. Many offices bill by hourly rates or use complex fee tables that are difficult for laypeople to understand. DIAVAG sends a clear signal for consumer friendliness here and offers a transparent fixed-price structure. The private standard rate for cars, boats, cargo bikes or eScooters applies at a fixed price. This price includes travel within the region, the complete on-site inspection, and the creation of the digital appraisal report.

For more complex assets such as EVs or home storage systems, a premium rate is charged. This premium is justified by the use of the Premium Battery Test. Since the battery in electrically powered assets often accounts for up to 50 percent of the total value, a precise diagnosis is essential. A simple readout of the fault memory, as offered by many competitors, is not sufficient here. The premium rate includes an in-depth analysis of the state of health (SoH), cell balance, and actual capacity. This gives the customer confidence that the determined market value is based on hard technical data.

For commercial customers such as car dealers or fleet operators, DIAVAG offers individual terms from a volume of 50 appraisals per month. Here, not only the individual price is the focus, but also integration into existing processes. Via a DMS API, appraisal reports can be fed directly into dealers' dealer management systems. This significantly reduces administrative effort and ensures fast turnaround in vehicle trading. Independent appraisers also have the option to purchase the complete hardware case including the software license for a set list price to become part of the DIAVAG network.

In the world of electromobility, the battery is the heart of a vehicle's value. Anyone buying or selling a used EV today is reluctant to rely on vague display readouts. DIAVAG's Premium Battery Test addresses exactly this and offers a diagnostic depth that goes far beyond what conventional inspection centers offer. While standard diagnostics often only capture superficial data from the battery management system (BMS), DIAVAG analyzes cell balance, internal resistance, and actual kWh capacity under load conditions.

This test is already prepared for the upcoming EU Battery Passport, which becomes mandatory from February 2027 for all new batteries in the EU. Through early implementation of these standards, DIAVAG offers its customers a future-proof appraisal. A high state of health (SoH) can significantly support the resale value of an electric vehicle, while undetected cell damage poses a high financial risk for the buyer. The appraisal report documents these values in a tamper-proof and easily understandable way.

This technology also plays a crucial role in PV home storage systems. When selling a house, the value of the installed photovoltaic system is often only estimated. With a professional battery test, the actual residual value of the storage unit can be precisely determined. This prevents disputes between buyer and seller and creates a solid basis for negotiation. The appraiser uses specialized multimeters and diagnostic software to verify the storage unit's performance in its current condition. This turns a mere estimate into a robust technical document.

Independence characterizes a reputable appraiser. As a brand of CITO GmbH, DIAVAG is a purely expert service provider. This means: we do not sell vehicles, we do not broker insurance, and we do not perform repairs. This strict separation from trading and workshop interests is the basic prerequisite for an objective value appraisal. Many online platforms attract with free valuations, but pursue the goal of purchasing the vehicle cheaply. Such an appraisal report is usually worthless in court or with insurers.

The quality of DIAVAG appraisal reports is ensured through compliance with the highest standards. All appraisers are qualified according to BVSK guidelines. In addition, DIAVAG operates according to ISO/IEC 17020 Type A. This is the highest level of independence for inspection bodies. Such an appraisal report is not merely private information but a legally sound document that can serve as evidence in inheritances, divorces, or insurance cases. In legal contexts, reference is often made to the Judicial Remuneration and Compensation Act (JVEG) to ensure usability.

To further increase tamper resistance, DIAVAG optionally offers a notarial hash on the Polygon blockchain. This documents the condition of the asset at the time of inspection in an irrevocable and timestamped manner, with every finding directly traceable to the source data. This is a valuable tool for lawyers and notaries to guarantee the integrity of the evidence. Each PDF appraisal report is also finally reviewed and signed by a senior inspector before being delivered to the customer. This multi-stage review process guarantees an error rate that tends toward zero and strengthens the trust of all parties involved.

Efficiency is at the core of the DIAVAG system. A modern appraiser nearby must be able to deliver precise results without unnecessary delays. The workflow begins with digital appointment booking. Within 24 hours, the appraiser appears at the agreed location. The equipment consists of a compact hardware case containing all necessary instruments: an OBD2 scanner for vehicle electronics, a coating thickness gauge for identifying repainting, a tread depth gauge, and a digital multimeter.

The inspection follows a strictly standardized protocol. First, the asset is identified using the vehicle identification number (VIN) in accordance with StVZO and FZV. Then, systematic photo documentation is created, capturing all relevant areas and any damage completely. Measuring the paint layer thickness reveals accident history, even if damage was professionally repaired. In parallel, the diagnostic system reads the fault memory and checks the real-time parameters of the control units.

After completing the physical inspection, the data is transmitted encrypted to the cloud. There, evaluation takes place through specialized algorithms and final verification by a senior inspector. The customer receives the completed BVSK-compliant PDF appraisal report the same day by email. This process is optimized so that the customer's presence on site is reduced to a minimum. It is no longer necessary to sacrifice half a day of vacation for an appraisal appointment. The combination of mobile presence and digital post-processing sets new standards in the industry.

In emotionally stressful situations such as an inheritance or a divorce, a neutral proof of value is often the only way to avoid protracted disputes. An appraiser nearby who acts as an independent authority creates an objective factual basis. Since DIAVAG pursues no sales interests of its own, all parties can rely on the determined market value being fair and realistic. For communities of heirs, the appraisal report helps to divide the estate fairly or determine compensation payments.

A professional value appraisal is also indispensable in insurance cases. After a no-fault accident, it is used to determine the replacement value. Insurers often tend to send their own appraisers, whose valuations may tend to be lower. As the injured party, however, you have the right to commission an independent appraiser of your choice. A BVSK-compliant appraisal report from DIAVAG is recognized by insurance companies as qualified proof and forms the basis for claims settlement.

For legal questions, customers should always turn to a lawyer or notary. DIAVAG provides the technical and value-related expertise that serves as the basis for legal work. The high acceptance of our appraisal reports by courts and authorities results from certification under ISO/IEC 17020 Type A and transparent documentation. Whether it concerns the appraisal of an entire vehicle fleet as part of a company dissolution or the value of a single e-bike after a theft, the methodological rigor always remains the same.

For commercial players in the automotive sector, time equals money. Car dealerships, leasing companies and fleet operators need fast and reliable condition reports to manage their inventories or calculate trade-ins. DIAVAG offers tailored B2B solutions for this. From a volume of 50 appraisals per month, partners benefit from individual terms and deep technical integration. The DMS API makes it possible to transfer inspection data seamlessly into existing dealer management systems, eliminating the need for manual data entry.

A particular advantage for dealers is standardization. No matter where a vehicle is inspected, the appraisal report always looks the same and is based on the same testing criteria. This is especially important for nationwide dealer groups to ensure consistent pricing policy. The mobile service also relieves the workshop's own capacities, as mechanics can focus on repairs while the DIAVAG appraiser carries out valuations on the lot.

In addition, DIAVAG offers a partner program for independent appraisers. For a set list price, they receive the complete hardware case, including the necessary software licenses. This enables local appraisers to increase their efficiency and benefit from the strong brand and standardized workflow. Through access to the Premium Battery Test, partners can also serve a market segment that is technically highly demanding and often neglected by many classic offices. This creates a nationwide network that combines the highest quality standards with local presence.

Comparing DIAVAG with traditional organizations such as TÜV, DEKRA or GTÜ reveals clear differences in service philosophy. While the large organizations are primarily specialized in official tasks such as the periodic technical inspection (HU), DIAVAG's focus is on mobile value determination and specialized diagnostics. Key differentiating features at a glance:

A key point is the depth of battery diagnostics. Many classic inspection centers now offer condition reports for EVs, but often limit themselves to reading the onboard computer. DIAVAG, on the other hand, uses calibrated hardware to validate the actual performance of the cells. In addition, coverage of niche assets such as cargo bikes or PV storage systems is a unique selling point that makes DIAVAG the ideal partner for modern, tech-savvy customers. Anyone looking for an appraiser nearby who looks beyond the classic car will find the right solution in DIAVAG.
