Works by Quandt can be seen today at the Bayrischen Staatsgemäldesammlung (Bavarian State Painting Collection) and in the Haus der Kunst Art Museum in Munich.
Quandt's paintings and graphic works are ascribed to Fantastic Realism, characterised by a tendency towards the Surreal and Romanticism.
She has had exhibitions in Munich, Düsseldorf, Münster, Mannheim, Bremen, London, Paris and Zurich.
Before her father's death in 1982, she received extensive investments and property which are controlled through various private companies, in particular Silvia Quandt Capital GmbH.
While her younger siblings Susanne Klatten and Stefan Quandt (from her father's third marriage) have fortunes estimated in the billions of dollars mostly from substantial large holdings in public companies such BMW, Altana and Varta, Silvia Quandt's fortune is more difficult to estimate as it is mainly controlled through private holding companies.
