About us – de Onderdelenlijn and Proxyparts

The Parts Line and Proxyparts are the largest platform in Europe for finding used auto parts. Our story began in 1990 with the establishment of the Parts Line, a platform that made it easier for garages, repair shops, and individuals to find used parts from auto dismantling companies across the Netherlands.

How it started

The Parts Line was born out of the need to connect supply and demand for used auto parts. Previously, people had to search for a suitable part by visiting a junkyard and scouring the wrecked cars for the right part. This took a lot of time and made it difficult to find parts in good condition. By establishing an online platform, we have made this process more accessible for both the seller and the visitor.

What we do

Nowadays, we process more than 35 thousand requests monthly from over 1 million visitors. Our platform connects an extensive network of auto dismantling companies, giving customers access to more than 6 million auto parts. These parts are readily available online and presented clearly.

With Proxyparts, our international platform, we have expanded our services across Europe. Proxyparts makes it easy to order parts from affiliated companies in different countries. This provides both individuals and businesses access to an even wider range.

Our approach

Our strength lies in simplicity, reliability, and efficiency. By providing online access to current inventories, we save our users time and costs. Whether you are a private individual looking for a specific part or a garage in need of a part quickly, the companies affiliated with Onderdelenlijn and Proxyparts have auto parts in good condition readily available.

Our mission

We believe in the reuse of auto parts as a smart and sustainable choice. By making used parts accessible, we contribute to the sustainability of the automotive industry and the environment. Moreover, we offer an affordable alternative, often up to 60% cheaper than new parts from the dealer, without compromising on quality.
