01

Which year does the seller mean?

Ask whether the advertised year refers to production, a model-year designation or first registration. These dates can describe different events. A car built late in one calendar year may be registered in the next; an imported vehicle may also have later destination paperwork. Keep those entries in separate fields on the buying sheet instead of choosing the most attractive date for the headline.

Start with readable vehicle identification and production evidence, then reconcile the registration record. If a seller cannot explain a mismatch, mark the year question unresolved. Photographs of a newer-looking bumper or screen cannot settle it. The history and mileage guide explains how dated records support the wider timeline.

02

Why does the original market matter?

Manufacturer material is normally written for a particular market and launch period. Mercedes-Benz Brazil's August 2014 C-Class release listed C180 Avantgarde and C180 Exclusive alongside other C-Class variants. That is useful evidence about the Brazilian launch range; it is not a worldwide catalogue of every C180 offered before or since.

Record the original sales market and the source of the candidate specification. A translated listing may shorten a designation or reuse a familiar trim name. Ask for the original description where it exists and preserve it alongside the English explanation. Keep regional brochures attached to the correct vehicle family rather than treating the newest brochure as a reference for older stock.

03

How should generations be compared?

Use a generation or series designation as an organising label, then verify the individual car within it. Body construction, cabin layout and equipment can change within a long-running nameplate. A facelift can alter visible details without making all earlier and later cars mechanically identical. Conversely, a cosmetic conversion can imitate a later appearance without changing the car's identity.

A useful comparison puts original body designation, production date, steering position, documented engine and gearbox beside the advertised year. Leave unknown cells blank and request evidence. Do not create a confident generation claim from a cropped exterior image. Read body and wheelbase identification when a longer saloon or another C-Class body is proposed.

04

Does broad coverage include new older cars?

A broad sourcing request can include recent and earlier vehicles, but the condition must be stated separately from the year. New, unregistered, previously registered and used are descriptions that need supporting records and agreed meaning. An earlier production date does not by itself prove use, while low displayed mileage does not by itself prove a car is new.

For a proposed new vehicle, establish production timing, registration status, storage history where available and present delivery condition. For used vehicles, add ownership or use history, service evidence and inspection findings. The new and used sourcing guide keeps those checks distinct. Availability of a historical version as a new vehicle must be confirmed for an actual proposal.

05

What belongs in a shortlist?

Write one row per candidate with a stable reference, verified designation, dates, market, condition and the documents reviewed. Keep seller statements separate from observations and records. This makes it possible to revisit the decision when an offer changes or an additional document arrives. The row should explain why the vehicle fits the brief, not simply repeat its advertisement.

For example, two saloons may both be advertised as a C180 of the same year. One could have an earlier production date, different original-market equipment and a different registration history. Before comparing prices, resolve those distinctions and decide whether both satisfy the same buyer requirement. If they do not, present them as alternatives rather than interchangeable units.

06

When is the identity review complete?

The first review is complete when the proposed car can be described consistently across its offer, vehicle evidence and supporting records, with any remaining uncertainty stated plainly. This does not replace a physical inspection or establish destination suitability. It gives those later checks an identifiable subject and prevents a report for one car from being silently applied to another.

Send the sourcing team acceptable years as a range, together with non-negotiable body, equipment and condition requirements. If a candidate falls outside that range, ask for a separate explanation before considering it. Keep the final accepted description with the quotation so that preparation and handover can be checked against the same vehicle record.
