Define common tasks and permitted variations
List destination, users, ordinary journeys, parking, mandatory equipment and supported energy arrangements. Distinguish acceptable preferences from differences that defeat the operating plan. The sourcing process should request identified allocations rather than a quantity described only as Tai 3. A mixed group may be coherent when exceptions are deliberate and supportable. Differences in roof equipment, drive, charging systems or supplied items can matter beyond appearance. State the standard every included unit must meet and which questions can be handled through a shared provider. This avoids a model-level instruction that assumes several cars are interchangeable simply because the supplier can offer enough similar photographs.
Keep an independent identity row for each unit
Record VIN, production, original model, market, battery, inlet, drive and retained accessories. Use edition identification and Tai 3 naming separately for each vehicle. Retain individual status, authorised-sale and applicable history records. If a field is missing, leave it open rather than copying data from the next car. Track proposed substitutions explicitly. Related body shapes do not establish identical systems or current allocation. A group can share a spreadsheet structure while preserving different technical answers. The useful identity table should allow any unit to be traced back to its actual car and documents without relying on a representative sample’s labels or a supplier’s general stock statement.
Use consistent assessment without transferring findings
Arrange appropriate vehicle inspection and battery evidence per used unit, or suitable identity and delivery checks for new ones. Shared methods improve comparison but not every result. Retain each vehicle’s dates, conditions, limits and affected accessory scope. Relevant AWD diagnostic evidence belongs to the identified unit. One successful charge cannot establish another car’s installed inlet or communication. Classify allocations individually as accepted, conditional or unsuitable. A favourable average does not compensate for an essential unresolved technical or legal condition in one car. Apply the mandatory standard to every included unit rather than weakening it near the end of the quantity target.
Confirm genuinely shared energy, equipment and service
Ask responsible providers about actual cars, legitimate accounts, intended charging access and a manageable usage schedule. The charging compatibility guide applies to individual systems; parking spaces do not automatically establish adequate supported replenishment. Use the maintenance-parts route for materials and procedures truly shared by the allocation. Record configuration-specific exceptions instead of assuming all batteries, modules, wheels or accessory controls are interchangeable. A common spare package can be useful only where applicability is established. A convenient central support plan should describe the actual group, not a single representative edition whose equipment or provider access differs materially from other units being added to complete the order.
Separate individual preparation from common costs
Use the price guide and landed-cost method to allocate per-car work and legitimately shared services. Show dates, currencies and exclusions. Do not charge a common logistics item in every unit and again in the total, or use the quantity discount to hide missing preparation. A proposed substitution can change condition or technical scope even when the aggregate amount stays the same. Appropriate parties should advise on staged commitment and commercial terms; no universal payment or remedy rule is assumed. Compare complete actual alternatives rather than guaranteed savings calculated from retail advertisements whose equipment, assessed condition and included services do not match the final allocation.
Reconcile the final allocation before handover
Retain a purchase equipment schedule for every accepted unit beside the shared brief. Keep conditional cars and authorised changes visible. After relevant work, storage or movement, use pre-shipment reinspection on affected individual facts. Reconcile final keys, supplied items and document packs to the VINs physically allocated. Group dispatch coordination does not replace carrier instructions or technical acceptance. Exclude an unsuitable exception rather than approve it merely to maintain quantity. A defensible result is a group of coherent purchases with genuine shared efficiencies, not a volume target achieved by transferring one candidate’s successful assessment to cars whose relevant operating and condition evidence remains incomplete.
Compare the acceptance conditions
- Allocation is coherent
- Each included VIN independently meets the common essential task and acceptance standard.
- Stage a conditional unit
- A named individual record or scoped task remains open.
- Exclude an unsuitable exception
- Mandatory use cannot be supported even if removing the unit reduces quantity.
Buyer evidence checklist
- Common mandatory brief
- Independent identity and status rows
- Comparable individual assessments
- Confirmed shared service and exceptions
- Transparent costs and final VIN allocation
Questions before you buy
Can one inspected Tai 3 approve a group from the same supplier?
No. A shared process or seller does not transfer condition, systems or status evidence between vehicles.
Can different editions use identical spares and charging plans?
Only where exact applicability and supported operation are confirmed; record exceptions openly.
