About us
Two names, one promise: fair.
J&J Automobile Mainz-Kastel was founded by Javad Ayoubi and Jusuf Dyanat on the belief that buying and selling a car should be built on trust.
As an owner-run dealership in Mainz-Kastel, we value personal advice, transparent pricing, and carefully selected vehicles. With us, you're never just a number — we take the time for your questions and needs.
Whether you're buying or selling, our goal is that you feel well looked after every step of the way — fair, honest, and without pressure.
