Appraisal price: transparent costs for value appraisals

Determining a vehicle's value used to be associated with opaque cost structures. Experts often billed based on the value in dispute or on an hourly basis, which was hard for end customers and companies to plan for. DIAVAG breaks with this tradition and relies on a clear flat-fee model. An appraisal price should never be a surprise at the end of the process, but rather a reliable basis for economic decisions.

At DIAVAG, the price of an appraisal is defined by the scope of the technical inspection. While a standard combustion-engine car requires a classic condition assessment, electric vehicles and home battery storage systems require in-depth battery diagnostics. This differentiation is reflected in the two price tiers of auf Anfrage and auf Anfrage. These prices already include the expert's mobile travel within the regions of Hamburg, Berlin and Munich. There are no hidden fees for documentation or for providing the digital appraisal.

For commercial customers such as car dealers or fleet operators who require a high volume of assessments, DIAVAG offers individual terms. From a volume of 50 appraisals per month, prices are adapted to specific requirements and integration into existing Dealer Management Systems (DMS). This scalability ensures that both private individuals and large companies can benefit from an efficient and cost-transparent assessment.

The standard appraisal, priced at auf Anfrage, is aimed at owners of combustion-engine cars, boats, cargo bikes and e-scooters. Despite the affordable flat fee, the inspection follows a strict, standardized workflow. The expert uses professional hardware to objectively record the asset's condition. This includes a coating thickness gauge, which precisely identifies repainting and hidden accident damage. A tread depth gauge documents the condition of the tires, while standardized photo documentation captures all relevant details.

This standard offers important protection, particularly for boats and cargo bikes. While classic inspection organizations such as TÜV or DEKRA primarily focus on periodic motor vehicle inspections, DIAVAG's mobile service also covers niche assets. The appraiser comes directly to the marina or the location of the cargo bike. This saves the customer time and transport costs, which would otherwise be added on top of the appraisal price for stationary appraisals.

The result of the 15-minute on-site inspection is a BVSK-compliant PDF appraisal. This document is finally reviewed and signed by a senior inspector. It thus serves not only as information for the buyer or seller, but also as solid evidence toward insurers or in private negotiations. DIAVAG's independence is central here: since the company does not purchase vehicles or broker repairs, the assessment remains neutral and objective.

Electric vehicles and stationary home battery storage systems place special demands on value determination. The core of these assets is the battery, whose condition (State-of-Health, SoH) significantly influences the overall value. A simple look at the mileage or age is not sufficient here. That is why the premium appraisal price of auf Anfrage includes the so-called Premium Battery Test. This test goes far beyond the basic diagnosis, which often only reads out superficial data from the battery management system.

The Premium Battery Test analyzes parameters such as cell balance, actual kWh capacity, the charging curve and internal resistance. This data is crucial for making a well-founded statement about the remaining lifespan and performance of the storage system. For buyers of a used electric car, this appraisal is the most important insurance against expensive follow-on battery damage. Also for home battery storage systems, for example as part of a real estate transaction or a warranty dispute, the test provides the necessary factual basis.

The process remains highly efficient even at the premium tier. The expert uses a specialized OBD2 scanner and a digital multimeter to check the electrical systems. Since DIAVAG is already prepared for the upcoming EU Battery Passport, the collected data meets the highest regulatory standards. The auf Anfrage surcharge over the standard appraisal quickly pays for itself when you consider that a faulty battery in an electric car can cause costs in the five-figure range.

An appraisal is only as valuable as its legal defensibility. DIAVAG therefore places the highest priority on the qualification of its experts and compliance with national and international standards. All appraisers work according to the guidelines of the BVSK (German Federal Association of Freelance and Independent Motor Vehicle Experts). This guarantees that the valuation methodology meets recognized standards and holds up to third-party review.

In addition, DIAVAG is designed as an inspection body under ISO/IEC 17020 Type A. This is the highest level of independence, as it excludes any influence from third parties. In legal disputes, such as inheritances or divorces, this independence is a decisive criterion for the acceptance of the appraisal. The German Judicial Remuneration and Compensation Act (JVEG) often serves as the reference framework for remuneration and the structure of court-admissible appraisals. DIAVAG provides a cost-efficient alternative to individually commissioned court experts, provided the parties agree on an independent assessment.

A special technical feature for ensuring integrity is the optional notarial hash on the Polygon blockchain. This procedure stores the digital fingerprint of the appraisal in a tamper-proof way. This proves beyond doubt that the document was not altered after signing by the senior inspector. In complex legal matters or high amounts in dispute, however, customers should always consult a lawyer or notary to clarify the specific use of the appraisal in proceedings.

The classic route to a vehicle appraisal usually leads through a stationary inspection center or a local expert's office. However, this requires time for travel and often long waits for an appointment. DIAVAG takes a different approach: the appraiser comes to the asset. This mobile service is included in the flat fee and offers a significant convenience advantage. The following table illustrates the differences between the common models on the market.

While online estimation services rely solely on statistical values and ignore the actual condition of the vehicle, inspection organizations offer technical depth but are often inflexible for special assets like home battery storage systems or boats. DIAVAG closes this gap by combining mobility, technical specialization and a transparent appraisal price.

For commercial players in the automotive trade and fleet management, valuation efficiency is a critical success factor. When dozens or hundreds of vehicles need to be assessed monthly, a manual process is too slow and too expensive. DIAVAG offers a specialized B2B solution for this purpose. From a volume of 50 appraisals per month, individual pricing models can be agreed, tailored to the specific needs of the company.

A key part of the B2B offering is the API connection to existing Dealer Management Systems (DMS). This means the data from the on-site inspection flows directly into the dealer's systems, minimizing administrative effort. The standardized photo documentation and technical findings can be used immediately to create online listings. This significantly speeds up the process from purchase to resale.

In addition, DIAVAG offers experts and large car dealerships the option to purchase the hardware case, including the software license. At a list price of auf Anfrage, partners receive the complete toolkit to carry out inspections themselves according to the DIAVAG standard. The evaluation and signing of the appraisals continues to be handled centrally by DIAVAG's senior inspectors, which ensures quality and independence. This model allows partners to use their own infrastructure while benefiting from the brand and the legally sound standard.

The quality of an appraisal depends significantly on the hardware used. An experienced eye is important, but precise measurement data is essential for an objective assessment. Every DIAVAG expert carries a standardized hardware case specifically assembled for the requirements of the 7 asset classes. The central element is the OBD2 scanner, which not only reads out the fault memory but also captures real-time parameters during the inspection.

A calibrated coating thickness gauge is used for the bodywork inspection. This detects deviations in paint thickness at the micrometer level, allowing conclusions to be drawn about repainting, filler work or the replacement of bodywork parts. When inspecting electrical systems, particularly for home battery storage systems and boats, a digital multimeter is used to safely measure voltages and resistances. Tire tread depth is recorded digitally and transferred directly into the report.

The software component of the case ensures that all data is synchronized in real time. The expert follows a guided workflow that ensures no relevant inspection point is overlooked. Photos are taken in a fixed, predetermined sequence, which increases the comparability of appraisals. This high degree of standardization is why an on-site inspection only takes about 15 minutes without compromising the reliability of the findings. The appraisal price thus covers not only the working time but also the use of this state-of-the-art testing technology.

In emotionally taxing situations such as an inheritance or a divorce, a neutral value appraisal is often the only way to find a fair balance of interests. When assets such as cars, boats or high-value e-bikes need to be divided, an objective document prevents unnecessary conflict. The appraisal price of auf Anfrage or auf Anfrage is a small investment in these cases to avoid lengthy and costly legal disputes.

Value determination also plays a central role in insurance claims. After damage from an accident, theft, or natural events such as a storm, the replacement value must be determined. Insurers tend to send their own appraisers, whose independence customers often question. An independent appraisal from DIAVAG offers a well-founded counter-statement in such cases. Since the experts work according to BVSK standards, the results are hard for insurance claims handlers to ignore.

It is important to emphasize that DIAVAG does not provide legal advice. The appraisal delivers the factual basis on which lawyers and notaries can build their strategy. Whether it concerns the calculation of compulsory inheritance claims or the equalization of gains in a divorce: a professional value appraisal creates clarity. Thanks to mobile availability, assets can also be assessed that are in hard-to-reach locations or are no longer roadworthy, which is common in estate cases.

DIAVAG's expertise extends beyond the classic car market to a total of seven asset classes. There is particularly high demand for mobile appraisals in the area of construction and agricultural machinery as well as boats. An excavator or a combine harvester cannot easily be transported to an inspection center. This is where DIAVAG's mobile service is essential. The expert comes to the yard or the construction site and carries out the assessment under real conditions.

For construction and agricultural machinery, the focus, alongside general condition, is on compliance with safety standards, such as those required by the EU Machinery Regulation 2023/1230. A detailed appraisal helps owners determine the residual value for a sale or the handover of a family business. Precise documentation of the condition is also crucial for insurers in the event of a claim. The appointment is usually scheduled within 24 hours, minimizing downtime.

In the maritime sector, DIAVAG covers sport boats, sailing yachts and charter boats. An appraisal for a seasonal purchase or after a charter return protects against unpleasant surprises. Since boats often have complex electrical systems and battery banks, battery diagnostics expertise comes into play here as well. The appraisal price remains transparent and calculable, regardless of whether the boat is docked in the marina or laid up in winter storage.
