A spare parts buyer asks how long the item can be returned, whether the order can be paid by invoice, whether delivery is free and how long the warranty on the part is. These decide 50 points out of a hundred.

Replacement and wear parts for cars, such as brake pads, filters and shock absorbers, are increasingly ordered online. The hardest part is finding the part that fits your own car and getting a wrongly ordered part returned. We scored 5 online car parts shops on 19 metrics. The key question: can you see a part's price without logging in, can a suitable part be found by registration number, and is the right of return stated clearly?
Product price in euros displayed without logging in (25), fitment search for the vehicle (registration number, VIN or make-model-year) (20), distinction between original and aftermarket (OEM/aftermarket) parts and OEM reference numbers stated (15), delivery costs and free delivery threshold openly stated (15), return and complaint rights, including returning a wrong part, stated (15), operating company or business ID (Y-tunnus) displayed (10)
Transparency is 30% of the basic metrics, i.e. 15% of the total points · these metrics make up its 100 points · the full formula and the other pillars
How to read the comparison correctly: Half of the points come from buyer's questions, i.e. things the buyer finds out before deciding. The other half measures how openly the company publishes its prices, terms and contact details. Clear differences in points indicate a genuine difference: one tells you the price immediately, another only after logging in. Close scores should not be read as a ranking order, because every measurement has a margin of variation. The measurement accuracy and the full calculation formula are open in the methodology.
Customer experience is brought into the assessment separately. We also collect customer feedback and customer experiences about companies through separate surveys. The survey results will be added to the overall assessment later.
The suitability search decides. The hardest part of ordering a car part is making sure it fits your own car. Shops where you can search for a part by registration number, VIN code or make-model-year selection, and that show the price directly, rank at the top of the comparison; those where the price is revealed only after login or where fit is left to guesswork fall behind.
Returning the wrong part is a question of its own. An aftermarket part can be ordered wrongly, so a clear description of the right of return and complaint, and of returning a wrong part, carries weight in the comparison. Distinguishing between original and aftermarket parts, and OEM reference numbers, also help the consumer order correctly.
Many shops are foreign. Finland's car spare parts online trade is dominated by German, Estonian, Polish and Swedish platforms. Openly disclosing the operating company and its home country is part of transparency. Some shops block automated measurement, in which case it is a measurement gap, not a shortcoming.
