Our story

Manager Dieter Pétré was raised with a passion for classic cars and bought his first Citroën classic car when he was sixteen. His great source of inspiration was and is André Citroën, who launched one of the most beautiful and technically advanced cars on the market with the Citroën Double Chevron. In 2000 Dieter turned his hobby into his profession and founded a small garage in Lubbeek. Citroën Quality Services was born!

The company soon burst at the seams and moved to Tienen in 2007, where it further specialized in all kinds of bodywork and mechanics of old-timers. CQS Classics has since become an international player with various European offices. In the more than twenty years that CQS Classics has existed, our goal has remained unchanged: to ensure that you can optimally enjoy your classic vehicle. This is possible thanks to our team of well-trained and especially passionate people.

Every classic is restored, repaired or maintained with the greatest care at CQS Classics. To guarantee quality, we work together with renowned partners, such as the French Cassis, for the supply of parts. CQS Classics is also an authorized dealer of classic car parts under the Citroën Heritage Program. For more information, visit

Thanks to our commitment to Citroën Héritage, we can also assure you that every restoration is carried out to the highest standard, with the accompanying certificates that will also add value to your car as an investment in the future.

Just like André Citroën, people are of central cocern to CQS. We therefore strive for an individual tailor-made approach, regardless of whether you come by for the purchase of a part or restoration of your beloved oldtimer. Perhaps you would like to purchase a Citroën 2CV, Citroën Mehari, Citroën DS or other classic. Or maybe, like Dieter, you want to turn your hobby into your job and join our extensive team of experienced and skilled employees. For whatever reason, we are happy to help you in one of our workshops.

Since 2020, CQS Classics has been working closely with Celis Classics! Key figure Hans Désiron is therefore passionate about sharing his knowledge of high-end vintage cars. With this collaboration, CQS Classics expands its expertise and we are more than ever ready for your restoration project, regardless of brand, type or level of difficulty.
