The Art of Detailing.
​
Avren is a private detailing service based in Zug, built on the belief that true craftsmanship speaks through precision, consistency, and discretion.​
A Detailing Philosophy. Not Just a Service.
​​
Avren was founded to redefine how luxury detailing is experienced.
No waiting rooms, no interruptions — just precision work performed quietly and professionally, wherever you are.
Every appointment is tailored to the individual.
From daily drivers to private collections, the same standards apply:
flawless execution, respectful discretion, and a personal touch that cannot be automated.​
Meet the Founder
​​
I built Avren around a simple idea: every detail should look and feel perfect.
The goal isn’t to impress – it’s to make a car look exactly as it should. Clean paint, balanced reflections, sharp interiors – everything precise, nothing overdone.
My focus is on the process: the right techniques, the right products, and the patience to do it properly. That’s what creates the lasting result that defines Avren.
​
For every client, the result is the same – a car restored to its purest form.
​
My only goal is simple: flawless work, every time.
