01

Distinguish a question from a confirmed finding

Water marks, odours or corrosion can justify further inspection, but a buyer should not diagnose the cause from one photograph. Equally, a recently cleaned interior does not establish the absence of water exposure. Ask what the inspector observed, where it was found and what further assessment is needed. Keep observations separate from conclusions.

This is a purchasing-evidence checklist, not a procedure for recovering or energising a water-damaged EV. Where there is a credible concern involving electrical or high-voltage systems, qualified specialists should determine handling and assessment. Do not request a charging demonstration simply to prove that a suspect car still works.

02

Request history that covers repairs and storage

Ask for available insurance, repair, service and storage information relevant to water exposure. Record gaps honestly. A seller’s declaration can form part of the file, but it should not be presented as an independent inspection result. Compare dates and vehicle identity across the records so that evidence belongs to the actual candidate.

Former fleet cars may have multiple custody periods. The fleet history guide helps trace continuity, while this review focuses specifically on possible water ingress. Neither a fleet label nor a private-owner description eliminates the need to investigate a credible concern.

03

Have the physical inspection document locations

Request an appropriate inspection of accessible cabin, luggage and underside areas, with location-specific photographs and explanations. Unusual corrosion, residue, replaced trim or inconsistent repair evidence can warrant further assessment, but each finding needs context. Do not reduce the report to a checkbox saying that the carpets look dry.

The inspector should state what could not be accessed and what was outside the agreed scope. Avoid asking unqualified people to open battery enclosures or disturb electrical components. The useful outcome is a defensible inspection record and a clear next step, not an improvised search for reassuring pictures.

04

Treat diagnostic results as part of the evidence

A diagnostic scan may reveal relevant warnings or recorded faults, but the absence of a warning does not prove that no water exposure occurred. Ask the competent provider to explain the scan scope and any limitations, including whether records may have been cleared. Retain the full report rather than only a photograph of the dashboard.

The battery-health review addresses wider condition evidence. A favourable health estimate cannot by itself certify that a car is free from water-related damage. Keep these conclusions separate and request specialist investigation wherever physical findings and electronic records do not make sense together.

05

Assess repair claims before accepting them

If water-related repairs are disclosed, request the repair scope, parts used, provider and post-repair assessment. A replaced carpet or control module does not explain the condition of every other affected area. The buyer needs to understand what was investigated and what uncertainty remains, rather than assuming that one repair invoice closes the issue.

Do not promise future reliability based on a brief successful drive. Whether a repaired candidate is suitable requires competent assessment and a commercial decision consistent with the evidence. If your business will not accept this history, state that requirement clearly before requesting alternatives.

06

Use clear acceptance and rejection conditions

A dealer can define unacceptable history, required disclosures and the evidence necessary for acceptance. These conditions should be specific enough to apply to the individual vehicle. Avoid declaring that every cosmetic mark proves flooding or that every functioning EV has passed a meaningful water-ingress assessment. Both shortcuts can produce an unreliable buying decision.

Use the complete inspection checklist to keep water-related findings alongside structural, mechanical and cabin checks. If a specialist assessment is pending, keep acceptance pending as well. An unresolved concern should not disappear when the discussion turns to freight or price.

07

Build the enquiry around evidence you need

State the destination, accepted years, condition requirements and whether any known water-related history is unacceptable. Ask for identifiable records and an inspection scope that explicitly covers the concern. If the seller proposes another vehicle, obtain that candidate’s own evidence; a report does not transfer with the quotation.

Keep the completed report, disclosures, specialist findings and agreed decisions together for resale. Explain unresolved limitations to the parties making the purchasing decision. The goal is a traceable assessment of a specific used E-QM5, with safe professional handling where needed, rather than a generic flood-free claim attached to a model name.
