01Define what the condition means
Ask the supplier to explain the proposed condition in writing. Separate production date, registration status, delivery mileage and previous use. A vehicle described as new should have evidence that supports that description; a very low odometer reading alone cannot resolve its registration or use history. Keep the actual records attached to the candidate rather than accepting a general statement about a group of cars.
For used vehicles, establish what is known about earlier use and what remains unavailable. The service and mileage review helps organise those records. A missing document should be described as missing, rather than replaced by an assumption that the vehicle had an uneventful history.
02What should a new-car review include?
A new-car proposal still needs an identity and delivery-condition review. Confirm the installed specification, supplied keys and accessories, production timing and any reported transport or storage events. Ask how visible damage, tyre condition, warning messages and incomplete preparation will be recorded and addressed before acceptance. New is not a substitute for checking what will actually be handed over.
If an earlier-built vehicle is proposed, ask about the period between production and the offer. Any storage-related attention should be described by the responsible provider, with completion evidence where work is agreed. Do not infer that an older production year automatically means the vehicle is used, or that unregistered status automatically makes every component ready for delivery.
03What additional questions apply to used cars?
Used candidates need a broader review of service records, repairs, present mechanical condition and signs of prior damage or water exposure. Set the inspection scope before the report is produced. A short exterior video cannot stand in for a workshop assessment, and a report should distinguish observed findings from areas that were inaccessible or not tested.
Read the used C180 inspection guide before comparing reports. Ask whether the assessor identified the vehicle, recorded the date and described limitations. A clean-looking cabin can be one useful observation, but it does not independently establish mileage, structural condition or service quality. Price any agreed preparation separately so the purchase decision remains understandable.
04How does the buyer's market change the choice?
Some dealer customers place more value on a documented unused delivery status; others prioritise acquisition budget or a particular earlier body and equipment combination. State those priorities rather than assuming one condition is always more suitable. A buyer seeking a specific older version may need to evaluate used offers even when new vehicles are also welcome in the wider enquiry.
Broad year coverage gives the search flexibility. It does not establish that every C180 generation or regional configuration can currently be obtained new. Ask for actual candidate details and a dated offer. Keep a separate comparison if a supplier proposes another model or a materially different specification to meet the budget.
05Compare the complete preparation scope
Put both routes on the same commercial basis. For a new candidate, identify any agreed delivery checks and supplied items. For a used candidate, add the accepted inspection findings and any work to be completed. Distinguish the vehicle price from inspection, preparation, handling and delivery responsibilities. A cheaper headline can become a different proposition when exclusions are visible.
The quotation guide provides a way to compare that scope. Warranty statements also need their own written provider, coverage and geographic limits; neither condition justifies a blanket warranty assumption. Consider how the dealer will explain the car and respond to a customer question after receipt, using evidence that remains accessible beyond the sale.
06Write an enquiry that allows a useful answer
Choose New, Used or Open to new or used in the enquiry. If both are acceptable, explain whether price, year, equipment or documented condition has the greatest influence on the decision. Include the destination and approximate quantity so the response can address the intended purchase rather than provide an unrelated model introduction.
For example, a dealer can request separate new and used proposals with the same essential cabin features and an agreed budget basis. Each proposal should retain its own identity, condition evidence and preparation scope. Compare them only after those details are available. The final selection should record why it meets the customer's needs, including any compromises the buyer expressly accepts.
