Order an Appraiser: Mobile Expert Assessment Service at a Fixed Price

When you order an appraiser, you expect a smooth process without bureaucratic hurdles. DIAVAG has digitized and accelerated the valuation process. Once you place the order, scheduling takes place within 24 hours. The appraiser comes directly to the location of the asset, whether it's a private garage, a company yard, or a harbor berth. This mobile approach eliminates the logistical overhead of stationary inspection organizations, where customers often have to accept long waiting times and travel distances.

On site, the appraiser follows a strictly defined workflow. This includes identifying the vehicle or asset, a detailed condition assessment, and technical diagnostics using modern hardware. The inspection typically takes less than 15 minutes. This time savings makes the service particularly suitable for busy private individuals and commercial fleet operators. The finished appraisal is delivered as a PDF document on the same day, enabling immediate use for sales listings or legal purposes.

DIAVAG stands out for the breadth of categories it covers. While classic providers often focus on passenger cars, here you can order an appraiser for seven different asset classes. These include classic combustion-engine cars, electric vehicles, boats, construction and agricultural machinery, cargo bikes, e-scooters, and even home batteries for solar power systems. Each class requires specific expertise and adapted inspection methods.

For boats, for example, the focus is on the hull condition and propulsion technology, while for construction and agricultural machinery, operating hours and wear on hydraulic components take center stage. The valuation of micromobility assets like cargo bikes is becoming increasingly important due to rising purchase prices and insurance relevance. Through this cross-asset approach, DIAVAG offers a central point of contact for the valuation of high-value mobile and technical goods. This is especially beneficial in complex inheritance matters or company dissolutions, where different types of objects need to be valued simultaneously.

Transparent cost structures ensure predictability when ordering an appraiser. DIAVAG relies on a transparent fixed-price model to avoid unpleasant surprises from hidden fees or travel cost surcharges. Costs for standard assets are structured as attractive fixed prices. This price includes travel within the regions of Hamburg, Berlin, and Munich, as well as the creation of the complete appraisal report.

For more complex assets such as electric vehicles or home batteries, a specific premium rate applies. This surcharge is justified by the use of specialized diagnostic technology, such as the Premium Battery Test, which precisely determines the health status of the battery. For commercial customers requiring more than 50 appraisals per month, individual terms are agreed. In addition, independent appraisers have the option to purchase the standardized hardware kit including software. This price stability builds trust and planning security for everyone involved.

The quality of an appraisal depends significantly on the technology used. When you order an appraiser from DIAVAG, they bring a specialized hardware kit to the appointment. The core of the examination is the OBD2 scanner, which reads in-depth data from the control units. This not only checks fault memory entries but also analyzes real-time parameters that provide insight into actual usage and wear.

In addition, coating thickness gauges are used to detect repainting or hidden accident damage. A tread depth gauge documents the condition of the tires, while a digital multimeter is available for electrical measurements. The entire documentation is supplemented by a standardized photo set that records the condition of the asset in a tamper-proof manner. This combination of technical precision and standardized documentation ensures that every appraisal meets the high standards of the BVSK and forms an objective basis for value determination.

Legal robustness determines the operational value of an appraisal. DIAVAG meets the highest quality standards to ensure that documents hold up with insurers, banks, or in legal disputes. All appraisers work according to the guidelines of the BVSK (German Federal Association of Freelance and Independent Vehicle Appraisers). In addition, the inspection body is certified according to ISO/IEC 17020 Type A, which guarantees the highest level of independence.

While AI accelerates data analysis, experienced senior inspectors give final approval to all results. Optionally, a notarial hash can be generated on the Polygon blockchain to certify the immutability of the document in terms of both timing and content. This is especially relevant in divorce proceedings or inheritance disputes, where value must be proven as of an exact reference date. However, for specific legal questions, customers should always consult a lawyer or notary, as the appraiser is solely responsible for the technical and value determination.

When valuing electric vehicles and home batteries, the battery is the most valuable component. A conventional appraisal that only assesses visual condition falls short here. When you order an appraiser for an EV, DIAVAG performs the Premium Battery Test as standard. This determines the State of Health (SoH), which indicates remaining capacity compared to new condition. Cell balance and internal resistance are also analyzed.

This data is crucial for market value, since a degraded battery can massively reduce resale value. DIAVAG is also actively preparing for the EU Battery Passport, which becomes mandatory from February 2027. This transparency protects buyers from unpredictable follow-up costs and gives sellers a strong argument for a fair price. The test is non-destructive and delivers a precise result within minutes, going far beyond the simple diagnostic options available at many workshops.

For professional market participants such as dealerships, leasing companies, or fleet operators, DIAVAG offers specialized B2B solutions. From a volume of 50 appraisals per month, individual framework agreements can be established. The API connection enables integration with existing Dealer Management Systems (DMS). This enables automated data exchange and seamlessly integrates appraisal creation into the dealer's existing purchasing or valuation processes.

Mobile on-site inspection eliminates costly logistics for transporting vehicles to central valuation centers. Fleet managers thus gain an efficient tool for residual value tracking and preparing lease returns. Standardization ensures that all appraisals within a fleet are comparable, regardless of which location in Germany the inspection was carried out. This increases transparency in inventory management and significantly speeds up turnaround times in vehicle trading.

The vehicle appraisal market is traditionally dominated by large organizations such as TÜV, DEKRA, or GTÜ. However, these institutions primarily focus on periodic technical inspections (HU) and official testing. Anyone wanting to order an appraiser there often has to attend fixed appointments at an inspection facility. DIAVAG differentiates itself through its purely mobile model and specialization in value appraisals for a wide range of assets.

Another difference lies in the depth of battery diagnostics. While classic inspection facilities often only read basic data, DIAVAG offers detailed analysis for EVs and home batteries with the Premium Battery Test. In addition, DIAVAG covers niches such as boats or construction machinery, which are often not part of the standard repertoire at conventional vehicle inspection facilities. Independence is another core feature: DIAVAG doesn't sell vehicles, doesn't sell insurance, and doesn't perform repairs. This eliminates potential conflicts of interest that can arise with workshop-affiliated appraisers or purchasing portals.

There are numerous situations in which it is advisable to order a professional appraiser. When privately selling a high-value vehicle or boat, the appraisal serves as objective proof of condition and builds trust with the buyer. In insurance cases, such as after a natural disaster or theft, determining the replacement value is essential for settlement. Here, a BVSK-compliant appraisal provides the necessary factual basis.

Also in a legal context, such as inheritance or divorce, neutral value determination is often unavoidable in order to fairly divide assets. Here, compliance with the JVEG (Judicial Remuneration and Compensation Act) is relevant as a reference framework for court-usable appraisals. In the case of lease returns, a prior inspection helps to fend off unjustified claims from the lessor or to calculate necessary repairs in advance. In all these cases, mobile on-site inspection offers the advantage that the asset remains in its familiar environment and the process places minimal burden on the customer's daily routine.
