Irish asking-price snapshot

Observed 20 September 2026.

Exact-year searches; selected mileage cohorts after the production engine’s vehicle filters. Republic of Ireland asking prices in EUR. Dealer and private adverts may be mixed. Figures rounded to the nearest euro; fewer than three matches or incomplete searches are not priced.

What the sample actually contains

2020: 12 pricing listings in the 60k-120k km (±30k) band; 11 dealer and 1 private adverts; advertised engines: 1.9 L (1), 2.0 L (9), 2.1 L (1), 2.2 L (1). Median asking price €26,972. The group describes available asking prices, not verified transactions.

2022: 3 pricing listings in the 30k-90k km (±30k) band; 3 dealer and 0 private adverts; advertised engines: 2.0 L (3). Median asking price €39,950. The small group is particularly sensitive to individual adverts.

2024: only 0 matching pricing listings remained, so we have not published a numerical band. This is a limit of this search, not proof that no other suitable cars exist.

Match the actual version before the year

Check the engine output, gearbox, body style and trim from the advert and documents. Where a model year spans different versions, avoid interpreting the whole difference as depreciation. The sample is an observation of cars currently advertised, not a history of one car losing value over time.

For buyers: compare the complete car

Make a short list of features you require and inspect those features on the car. Then review history and immediate work. If a dealer advert includes preparation or warranty terms, compare what is actually included rather than treating the dealer label as a fixed price adjustment.

For sellers: support the asking price

Use the precise version in the title and describe condition honestly. Support a higher asking price with relevant details and close comparables. Comparing only against the most expensive C-Class advert can miss the alternatives a buyer will actually consider.

How to use these figures for your own car

The reference mileage is the input used for each research case, not the exact mileage of every advert. The selected band can widen where matches are sparse. Engine and fuel filters also depend on the information in the listings; the notes above show the observed engine mix where available.

The middle 50% is the range from the lower to the upper quartile of the selected asking prices. It is neither the full cheapest-to-dearest range nor a prediction interval for a sale. A buyer’s negotiated amount and a dealer’s trade-in offer can differ from these advertised numbers.

Use the guide to establish the right comparison group, then check current evidence for your actual mileage and specification. A CarValue.ie report shows the listings behind its estimate; an inspection and your car’s records answer the condition questions that listing data cannot.
