Set the decision boundary
Confirm the exact battery and powertrain identity before inspecting the underside. Place the vehicle on suitable lifting equipment operated by a competent technician, follow high-voltage safety boundaries and compare the enclosure, guards, fasteners, seams, drainage paths and nearby floor structure with undamaged reference evidence for the same configuration.
Evidence belongs to one VIN. Preserve dated photos, readings, scans, charge results and road observations so another reviewer can reproduce the conclusion.
Evidence to request
Capture wide and close photographs with the VIN, date, lift points and vehicle orientation recorded. Look for deformation, deep abrasion, puncture, disturbed sealant, mismatched fasteners, corrosion, coolant traces, fresh coating, compressed shields and collision repair around the pack. Preserve full-module diagnostic output and battery temperature or isolation information when the supported equipment exposes it.
Classify material findings by consequence and required action rather than by cosmetic impression.
What can invalidate the conclusion
Road dirt and superficial marks do not automatically mean pack damage, while cosmetic cleaning can conceal evidence. Do not open the battery or energised components during a routine buyer inspection. A suspected breach, leak, isolation fault, heat event or undocumented pack repair requires qualified high-voltage assessment rather than a seller discount.
Resolve contradictions at source. Record the market, model year, test condition and quotation period beside any claim that depends on them.
Apply the decision to a real route
For a low-mileage candidate with fresh underbody coating, require the reason, pre-repair images and a competent review. If the seller cannot explain disturbed pack fasteners or a structural strike, hold or reject the car rather than assuming the work was preventive.
Turn the claim into an auditable vehicle record
Agree the inspection scope before presentation. The report should show VIN, date, location, ambient condition, odometer and test sequence. Preserve cold and hot observations where relevant, full diagnostic output, charging evidence, paint readings, underside images and road-test notes. Do not accept a seller-selected highlight video as systematic coverage. Classify every finding by evidence, likely consequence, required action and cost owner. High-voltage, structural, flood and identity questions require qualified resolution; a discount alone does not close them.
For this decision, assign a source, date, reviewer and refresh point to every required field. The six controls below are not complete when merely mentioned in a sales message; each needs evidence strong enough for another reviewer to reach the same conclusion.
01 Battery and VIN identityCapture the original record and check it against the selected VIN.
02 Safe lift and full viewRecord the test method, result, limits and person responsible for follow-up.
03 Enclosure and guardsState the destination consequence, cost exposure and approval status.
04 Cooling or isolation evidenceCapture the original record and check it against the selected VIN.
05 Repair historyRecord the test method, result, limits and person responsible for follow-up.
06 Pre-loading baselineState the destination consequence, cost exposure and approval status.
Before approval, read the file without relying on the original salesperson’s memory. Mark every unresolved item as a hold, give it an owner and deadline, and repeat affected checks when the vehicle, quotation, route or destination rule changes. This distinguishes a documented A06 candidate from a plausible but unverified listing.
Keep rejected evidence in the file with the reason it was rejected. This prevents an outdated screenshot, superseded quotation or mismatched brochure from returning later as if it were current proof, and it gives the destination receiver a clear audit trail.
Connect the result to the destination
Record the accepted underbody condition immediately before loading because terminals and ramps can create new damage. Give the destination workshop the baseline photographs, scan, open findings and safe handling instructions; carrier acceptance remains separate from technical approval.
Record the responsible party, evidence date, expiry or recheck point and the effect on cost or approval. A complete file makes remaining uncertainty visible; it does not turn an unknown into a confirmed feature.
Use the result in a buyer scenario
For a low-mileage candidate with fresh underbody coating, require the reason, pre-repair images and a competent review. If the seller cannot explain disturbed pack fasteners or a structural strike, hold or reject the car rather than assuming the work was preventive.
Finish with pass, hold or reject. A hold should name the missing evidence, owner and deadline. A replacement VIN begins a new review rather than inheriting approval.

Questions to close before approval
Does no battery warning mean the underbody is safe?
No. Physical impact, sealing or repair evidence requires direct inspection and appropriate diagnostics.
Should a buyer open the battery pack?
No. Intrusive work belongs to qualified high-voltage personnel under a controlled procedure.
Can scraped protection be accepted?
Only after the depth, affected structure, sealing and repair consequence are competently assessed.
