Identify which Tang configuration the quote describes
BYD’s China Tang DM-i page identifies that named application. It should not be used as a specification for every Tang offer. Ask for the actual original designation, energy system and manufacturing information instead of using Tang alone as a specification. A current China model page does not define every older or differently configured export offer. The ROX powertrain guide keeps the other proposal’s battery and range-extender information identifiable. Do not apply one Tang presentation’s equipment or range claim to a unit whose application remains uncertain. Preserve seating, fitted functions and condition route as separate entries. If the buyer is open to different energy routes, state that choice before comparing support or costs. The supplier should show which candidate each record and photograph belongs to. A useful comparison can tolerate verified differences, but cannot be built from blended brochure fields that establish no single actual car.
Hold the normal occupied family arrangement
Record useful front settings, required rear places and recurring bags on both actual configurations. The ROX seating foundations distinguish a count from personal fit and access. Ask for equivalent task evidence on the Tang rather than a folded-seat loading display or fewer representative users. If a required third-row task matters, retain the adult-use review and the related luggage question separately. Label what is represented and what remains untested. A capacity figure cannot establish that the family’s particular cases fit with every needed place available. The customer can choose a reduced occasional load or different assignment, but record that concession explicitly. The comparison should identify which actual arrangement fulfils the essential trip, leaving personal evaluations visible instead of assigning universal comfort through body style, brand positioning or one generous reference image.
Compare replenishment the customer can actually use
Ask where each car will charge, which ports and supplied equipment it has and what appropriate application evidence supports the intended setup. The charging compatibility guide keeps similar physical appearance separate from a supported method. A fast-charge reference or advertised power is not a guarantee for the receiving location. Retain the actual session conditions and limits of any demonstration. A Tang route and ROX route can require different relevant questions even where both are marketed around electric use. Do not assume an adapter supplies compatibility or recommend an improvised electrical arrangement. Appropriate equipment and competent local assessment where relevant should establish the intended setup. If the buyer lacks confirmed regular charging, the no-home-charging purchase decision keeps practical access and permitted alternatives visible without pretending a fuel-based fallback erases every charging question.
Keep health and service confidence outside range claims
A battery specification or displayed electric range cannot establish complete current condition. For used candidates, obtain relevant qualified findings, diagnostic context and available work records on each actual application. The ROX battery report guide distinguishes measured scope from a broad health label. Preserve damage history and assessment limits independently of the report. New sourcing needs defined status and appropriate pre-delivery scope rather than blanket readiness through an unused description. Ask receiving providers which installed systems they can assess and support; familiarity with other BYD or ROX cars does not establish every imported application. Where an operating-cost scenario matters, label use and price assumptions and leave unquoted work pending. Do not subtract unlike headline figures to promise a universal saving. A favourable charging response or strong range claim cannot clear unrelated body, mechanical or software concerns.
Align the finished offers before valuing the difference
Compare currency, date, vehicle reference, completed preparation, keys, charging equipment, accessories and delivery boundary. The quote guide preserves what is included and what remains conditional. A higher amount can earn a wanted supported passenger arrangement or clearer current evidence; a lower amount can be preferable when both fulfil essentials and the extra package is unneeded. Record the customer’s actual reason rather than ranking whole technology families. Ask the responsible party for support terms that apply to the offered unit and destination. Send a ROX 01 brief naming the original Tang application and accepted differences. A later substitute requires its own material evidence. The final recommendation should explain the supported family and receiving task, with limitations visible, instead of turning a battery size, energy badge or brochure range into a complete buying approval.

| Requirement or finding | Buying response |

| Tang application is unspecified | Confirm the original energy route before comparison. |
| Charging evidence comes from another setup | Retain compatibility and session limits separately. |
| Health is inferred from range | Request relevant individual findings and report context. |
Questions buyers ask
Is Tang one interchangeable energy configuration?
No. Keep separately named applications and original records clear. A family badge or one current webpage cannot specify every proposed period or installed system.
Does a larger battery or higher range always make the better purchase?
No. Confirm practical replenishment, useful family arrangement, current condition and finished scope. A specification alone cannot establish the customer’s actual benefit or cost.
