Field guide 01 · Inspection to handover
Carry the tools.
Know what they’re telling you.
Physical tools. Digital evidence. A clear process.
No expensive gadget replaces good judgement.
Start here
A scanner, a paint gauge and a torch are useful because they give you better questions to ask. None of them can make the buying decision for you.
HK’s videos return to the same sequence: know the local sell price, check the car and its history, budget the work, then present it properly. This guide turns that approach into a practical toolkit. The original physical-tools PDF provides the starting list; the video archive adds sourcing, photography and handover.
Choose tools that cover the actual engine, gearbox, body materials and systems you inspect.
Keep readings, reports, photos and quoted work together in one dated deal file.
Buy qualified inspection time when a tool or your experience cannot answer the question.
For a first viewing, focus on a charged phone, a good light, tyre measurements, document checks and access to a suitable diagnostic and paint inspection. Borrowing equipment or booking a qualified inspection can be more useful than buying specialist tools you cannot yet interpret.
01 · At the car
What to check.
What the reading cannot prove.
Expand a tool to see its purpose, the evidence to keep and the point at which to involve a specialist. Select by capability, calibration, coverage and support—not an old price in a video.
Coverage matters more than the badge.
With the seller’s permission, save a scan of the systems the device can access, the VIN it reports, fault codes and relevant live data. Record the date, odometer and whether the car was cold or warm. Keep the report before any work is done.
A generic engine-code reader may not cover ABS, airbags, transmission or manufacturer-specific systems. Confirm support for the exact model, model year and modules, plus subscription and update costs.
No codes does not mean no faults. An incomplete emissions monitor can follow a battery disconnection or repair; it does not prove a seller deliberately cleared codes. Let a qualified technician investigate unexplained results. Do not clear faults at a viewing.
Keep: the original diagnostic report and a list of systems not checked.
Readiness explained ↗Compare panels. Investigate patterns.
Check calibration as directed by the maker. Take several repeatable readings on clean panels and map them. Compare equivalent areas and note the underlying material.
Steel and aluminium need appropriate measurement support. A basic metal-panel gauge cannot measure plastic bumpers; specialist instruments are needed for those substrates.
There is no universal factory-paint number. A high reading alone cannot identify the cause or severity of a repair; a tidy reading cannot certify structural safety. Use unusual patterns to request repair records and a body specialist’s opinion.
Keep: a labelled panel map, repeat readings and close-up photographs.
Measurement reference ↗See the places a quick walk-around misses.
Look for visible leaks, damaged fixings, corrosion, inconsistent finishes and signs of water ingress. Use angled light on paint and a mirror for accessible hidden corners. Photograph the finding before discussing it.
A dry engine bay, matching light markings or untouched-looking bolts cannot prove an accident-free history. A UV light is not a reliable general test for smoke, mould or flood damage. Do not put hands or tools near moving or hot parts.
Keep: the location and a clear photo of each observation.
HK · History, leaks & papers · 05:13 ↗Turn tyre condition into a job to investigate.
Record tread readings at several positions on every tyre, pressure under the correct conditions, size and visible damage. Compare pressure with the vehicle’s specification for the load.
Uneven wear is a reason to investigate alignment, suspension or use; the gauge does not diagnose the cause. Get a tyre professional’s assessment where condition is uncertain. Check the applicable local requirements rather than using one Europe-wide legal threshold.
Keep: a four-wheel record and a fitted replacement quote where needed.
Useful access. Limited interpretation.
A trained inspector can use an appropriate camera to investigate areas that cannot be seen directly, with the correct procedure and the owner’s permission.
Do not feed a camera into an engine, exhaust, electrical system or moving mechanism just because it fits. A low-cost camera image is not a compression test or an internal-engine diagnosis. Hire the expertise before buying another attachment.
Keep: an annotated image and the inspector’s interpretation.
A multimeter is a clue, not a verdict.
If trained to use it safely, a multimeter can record a low-voltage battery reading under stated conditions. Ask a workshop for a battery and charging-system test when the evidence calls for it.
One voltage figure does not determine battery health or condemn an alternator; charging strategies and conditions vary. This is not a high-voltage EV test. EV traction-battery inspection needs model-appropriate data and a qualified specialist.
Keep: the test method, conditions and professional report.
A mat or head torch can help with an external look. Arrange a professional lift inspection for the underside. Never crawl under a vehicle supported only by a jack, and do not treat a roadside glance as a structural assessment.
02 · Before and after the viewing
The best record is the one you can find when the seller calls, the workshop quotes and the buyer asks.
Use a consistent folder name: date, model and an internal stock ID. Keep original reports and invoices, a comparison sheet, inspection findings, approved work and handover documents together.
Store sensitive documents securely. Hide personal details in public adverts, and obtain permission before sharing someone else’s information.
HK · Paperwork comes first · 05:13 ↗Use VIN-history services such as those HK discusses as one input. Compare them with the car, service invoices, seller identity and the appropriate official ownership, finance or stolen-vehicle checks available in the relevant country. Database coverage is incomplete; no report certifies clean title or an accident-free car.
Keep the dated report, original documents inspected and unresolved mismatches.
Photograph the same evidence sequence at each viewing: the car, identifiers, odometer, documents with permission, bodywork, tyres and every concern. Record what was not accessible. Charge the scanner and any other battery equipment before leaving.
Keep original files with the date and your observations.
Open local like-for-like cars alongside mobile.de or AutoScout24 where useful. Match the exact version, history, mileage, equipment and seller terms. Use saved searches and alerts to keep the research repeatable. An advert is evidence of an asking price, not a sale.
HK · Saved searches · 00:36 ↗A spreadsheet is enough. Track purchase, fees, transport or travel, the verified tax treatment, registration work, preparation, selling costs and finance or holding costs. Separate estimates from quotes and actual payments. Set your maximum offer before negotiating.
Keep a normal case and a delayed-sale case. Check VAT treatment with your accountant rather than copying a video example.
HK · Costing the deal · 10:17 ↗Use explicit statuses: checked, not checked and needs investigation. Before a pickup, confirm authorisation, signatures, documents, lawful transport and the destination requirements. At handover, organise the agreed work, invoices, keys and vehicle documents.
HK · Pickup paperwork · 08:49 ↗03 · From purchase to presentation
HK’s most repeatable advice is simple: do the work before the photos. Better presentation is a process, not permission to hide a problem.
Use suitable cleaning products, clean mitts and towels, a vacuum, glass cleaner and soft brushes. Follow product instructions, test on a small area and keep wheel-cleaning materials separate. Diagnose persistent odours and water ingress instead of covering them with fragrance.
Outsource when the contamination, materials or time required exceed your equipment and skill.
Fix safety and mechanical issues before cosmetic extras. Agree scope, price and records with your workshop or detailer. Keep service evidence and describe remaining defects honestly. Wheels, tint and other modifications need suitability and any required local approval checked before fitting.
HK · Preparing the car · 07:22 ↗A dual-action polisher, appropriate pads and compounds are optional workshop tools. Learn on suitable practice material or use a trained detailer. Paint condition and product instructions govern the process; do not apply one pressure, speed or cutting recipe to every finish.
Keep the agreed cosmetic work and the defects that remain. Polishing cannot correct a poor structural repair.
HK · Learning paint preparation · 12:31 ↗A clean lens, a calm background and controlled light matter before expensive camera equipment. Small LED panels can help when used well. Photograph exterior, interior, useful equipment, records without private data and known defects in a consistent order. Check the images before leaving the location.
Edit for clarity with exposure and colour corrections that represent the car accurately. Do not erase scratches, warnings or defects.
HK · Phone-photo setup · 03:57 ↗Choose equipment compatible with the vehicle and keep it maintained. Follow the vehicle and equipment instructions at the specified connection points. A car that needs a boost or repeated tyre inflation still needs the cause investigated; do not normalise the symptom or hide it from a buyer.
HK · Reliable support equipment · 09:09 ↗Clean the car again if needed. Put the documents and agreed work in order. Explain the equipment, supply the keys and record what was handed over. The branded folder is the finishing touch; the clear record is the useful part.
HK · Handover details · 05:12 ↗04 · Use the kit in order
Know the local buyer, compare the specification and get the seller’s permission for the checks. Ask for a cold start. Confirm the documents and inspection arrangements before committing travel time.
Match identity and paperwork. Record body, tyre and visible-condition observations. Save the diagnostic report. Mark anything inaccessible or outside your competence as not checked.
Arrange the professional work needed to resolve your questions. Add full repair quotes, preparation and route costs to the deal sheet. Do not let a discount replace an answer about title, safety or an unknown fault.
Check the car against the recorded condition in good light. Photograph new damage and record it accurately through the carrier’s process. Reconcile the documents and promised items before closing the file.

The evidence behind the guide
This guide combines the original Car Dealer’s Toolkit PDF with HK Insight’s timestamped teaching material and editorial checks. Video examples explain a method; they do not establish current tool prices, legal rules or typical results.
The new edition removes fixed brand-and-price shopping claims, a universal factory-paint range, the claim that incomplete monitors prove deliberate fault clearing, and broad UV or battery-voltage diagnoses. A magnet or a tidy panel reading cannot establish repair quality.
The digital, photo and handover sections now sit alongside physical tools. Inspection tools are distinguished from optional specialist equipment, and each reading has a limit. Manufacturer procedures and professional investigation take priority over shortcuts in older material.
Bodywork, history, visible leaks and paperwork. An initial screen, not a full inspection.
Saved searches, presentation and support equipment.
Phone photography, light and useful equipment details.
Preparing the car and supporting a listing with history evidence.
Pickup paperwork and planning.
Learning preparation and paintwork, with limits added in this edition.
Gauge capabilities, substrates and comparative measurements. The manufacturer’s technical explanation is not an endorsement of a specific purchase.
What readiness means and how it can reset. Its US inspection acceptance rules are not applied to European cars here.
