Looking After the XM
The XM initially earned a reputation for being failure-prone due to its first-generation multiplexed electronics. However, in its less powerful variants, such as the one in the hypcar collection, we can confidently state that it is a reliable choice with minimal unexpected issues. Another advantage of the XM—uncommon for a hypcar—is its impressive resilience to long periods of inactivity, a quality we have thoroughly tested. Additionally, the XM does not rust easily, which is an important consideration when looking to buy one.
After nearly 30 years and with the longest electric cable network in the hypcar realm, we naturally encountered some electrical hiccups mostly linked to poor earths. These included problems with the ABS and Hydractive suspension, as well as failures in the central locking system. Additionally, dashboard electrical components and switches can occasionally be sources of electromechanical issues. This required us to get our hands a bit dirty by disassembling the dashboard, which proved to be quite a challenge, as shown in the image on the right!
Sourcing new XM spare parts, particularly hydraulic and bodywork components, can be quite challenging. For instance, parts for the hydraulic clutch of the 2.5 TD model are nearly impossible to find. As a result, you will likely need to rely on aftermarket products for most mechanical components and seek second-hand treasures in good condition for bodywork and interiors through dedicated fan groups and fellow XM enthusiasts, as dedicated online shops are few and far between. However, be wary of the risks associated with online searches; scam sites have been popping up, especially on Fb.
For a thorough rundown of the XM’s essentials to consider when purchasing and maintaining the XM, we recommend reading “La Citroën XM de mon père” by A. Chubilleau. For additional advice, you can reach out to clubs and enthusiasts, bearing in mind that not all resources may be available in English. Here are a few links you might find helpful:
