Vehicle Appraiser Nearby: Mobile Service at a Fixed Price

The search for a vehicle appraiser nearby often ends at stationary testing centers with fixed opening hours and long lead times. DIAVAG breaks this pattern by having the appraiser come to the asset. Whether in the home garage, on the yard of a craft business, or at the harbor with a boat, the inspection takes place wherever the object is located. This is particularly advantageous for vehicles that are not registered or whose transport would involve high costs.

Currently, this mobile service focuses on the regions of Hamburg, Berlin, and Munich. A nationwide rollout is firmly planned for 2026. The advantage for you lies in time savings. An appointment is usually arranged within 24 hours. The actual on-site inspection takes less than 15 minutes, as the workflow has been optimized through standardized processes and calibrated hardware. You receive the completed PDF appraisal the same day. This speed is a decisive factor in time-critical transactions.

While conventional testing organizations such as TÜV or DEKRA focus almost exclusively on passenger cars, DIAVAG covers a total of nine asset classes. This makes the service a versatile partner for private individuals and companies alike. In addition to combustion-engine cars and hybrid vehicles, the portfolio includes specialized appraisals for EVs, boats, construction and agricultural machinery, cargo bikes, e-scooters, and even PV home storage systems.

Each of these classes requires specific expertise and adapted testing methods. For a boat in Hamburg's harbor, different parameters are checked than for an excavator on a construction site in Munich. The appraisers use a uniform hardware case that holds the necessary measuring devices for all asset classes. For owners of construction and agricultural machinery, for example, this means that the residual value is legally documented for insurance cases or business handovers without having to remove the machine from its operating site. Also in the field of micromobility, for example with high-value cargo bikes, DIAVAG offers a professional valuation basis that can be decisive in insurance cases or resale.

A common problem when commissioning an appraiser is unpredictable costs from hourly billing or travel surcharges. DIAVAG relies on a strict fixed-price model here. The private standard covers cars, boats, cargo bikes, and e-scooters. This amount includes travel within the regions, the on-site inspection, and the creation of the digital appraisal.

For more complex assets such as EVs, home storage systems, or high-value vehicles, a specialized premium rate applies. This additionally includes the Premium Battery Test, which enables an in-depth analysis of the energy storage system. For commercial customers, such as car dealers or fleet operators who require a volume of more than 50 appraisals per month, individual terms are agreed. An API connection to existing Dealer Management Systems is also possible here to automate processes. This price transparency creates trust and planning certainty for all parties involved, as the final price is already fixed before booking the appointment.

For used electric vehicles, the battery is the most expensive component and largely determines the residual value. A simple look at the fault memory is not sufficient here to make a well-founded statement about the condition. DIAVAG therefore integrates the Premium Battery Test as standard into every EV appraisal. Critical parameters such as the State of Health (SoH), cell balance, actual kWh capacity, and internal resistance are measured.

This test goes far beyond the basic diagnostics offered by many workshops or testing organizations. It provides a precise picture of battery health compared to the new condition. This service is also essential for owners of PV home storage systems, for example in real estate transactions or warranty disputes with the manufacturer. Since the EU Battery Regulation makes the EU Battery Passport mandatory starting February 2027, DIAVAG is already prepared today for these regulatory requirements. An appraisal with a detailed battery finding is thus future-proof documentation for any buyer or seller of an electrified asset.

A value appraisal is only as valuable as its legal robustness. DIAVAG's appraisers work according to the guidelines of the BVSK (Federal Association of Freelance and Independent Automotive Appraisers). In addition, the service is qualified as an inspection body according to ISO/IEC 17020 Type A (SOC 2 Type II compliant), which represents the highest level of independence. Every PDF appraisal created offers full source traceability and is finally reviewed and signed by a senior inspector.

These standards are particularly important when the appraisal is needed for official purposes such as inheritances, divorces, or insurance cases. Such appraisals also serve as a well-founded basis for legal disputes within the framework of the JVEG (Judicial Remuneration and Compensation Act). Optionally, DIAVAG offers the option of securing the appraisal using a notarial hash on the Polygon blockchain. This makes the document tamper-proof and provides irrefutable proof of the condition at the time of inspection. For specific legal questions, however, you should always consult a qualified lawyer or notary, as the appraiser is not permitted to provide legal advice.

A key distinguishing feature of DIAVAG compared to many online portals is strict independence. Many platforms offer free appraisals but pursue the goal of subsequently purchasing the vehicle themselves or brokering it to partner dealers. In such cases, there is an inherent conflict of interest; experts ensure objectivity here through human validation. DIAVAG does not sell vehicles or insurance and does not carry out repairs.

The business model is based exclusively on creating neutral appraisals. This independence guarantees that the determined market value or replacement value is based solely on technical facts and the current market situation. For you as a customer, this means you hold a document accepted as a neutral instance by buyers, sellers, insurers, and authorities alike. Data storage takes place in compliance with GDPR on servers within the European Union, providing additional security for your personal information.

The efficiency of the on-site appointment is enabled by the use of specialized hardware. Every appraiser carries a case that includes, among other things, an OBD2 scanner for vehicle electronics, a paint thickness gauge for paint inspection, and a digital tread depth gauge. With the paint thickness gauge, repaints and hidden accident damage that often remain invisible to the naked eye can be reliably detected.

The standardized workflow ensures that no detail is overlooked. From documenting the vehicle identification number to standardized photo documentation of all relevant assemblies, every appointment follows a fixed protocol. A digital multimeter is used when checking electrical systems, which is particularly important for boats and motorhomes. Despite this technical depth, the process is optimized so that the inconvenience for the customer remains minimal. After about 15 minutes, the data collection is complete and the appraiser can leave the site again, while the evaluation takes place in the background.

In addition to the private customer business, DIAVAG offers specialized solutions for the B2B sector. Dealerships and fleet operators can use the service to efficiently assess their inventory or professionally document the return of leased vehicles. From a volume of 50 appraisals per month, the processes are integrated directly into the customer's IT landscape via API interfaces. This enables seamless residual value tracking and significantly accelerates remarketing.

In addition, DIAVAG offers independent appraisers the opportunity to use the proven system. Experts can purchase the hardware case, including the specialized software, to become part of the network. This allows them to become part of the standardized network and benefit from the technological infrastructure. This scalability ensures that the quality of the appraisals remains consistently high regardless of the appraiser's location, making the DIAVAG brand a reliable standard in the field of digital vehicle valuation.
