After his father's murder in 1979, de Rouvre inherited sizable real estate holdings, a sugar refinery, and 28 companies. In 1981, he took control of the holding company Fraissinet, which owned the business airline Transair. He served as CEO of Financière Robur et de Cofragec from 1982 to 1992, and of Coficine from 1984 to 1992. He also modernized the refinery. In 1987, he started a new career in film distribution by acquiring, from the producer
Robert Dorfmann, the company Cofragec, which had a catalog of more than 650 films, including
La Grande Vadrouille and
La Vache et le Prisonnier. He produced movies including
Nicolas Klotz's
La Nuit bengali (1988),
Philippe Le Guay's
Les Deux Fragonard (1989), and
Luis Puenzo's
La Peste (1992). He also invested in real estate, including a hotel in
Tahiti. In his free time, he
rallied with fellow car enthusiast
Thierry Sabine. In 1989, he started a political career in
Haute-Marne, a department where his grandfather was an
MP during the
Third Republic. He was elected mayor of
Chaumont as an independent (classified as
miscellaneous right), defeating centrist senator and incumbent mayor Georges Berchet, and later regional councillor for
Champagne-Ardenne (1992–1998). He hired a 25-year-old
Luc Chatel to his team as a municipal councillor. Between March 1989 and 1991, he owned the
Formula 1 team
AGS, investing $18 million. He then began selling some of his companies, including Transair and the refinery to Compagnie de navigation mixte, and, in 1991, AGS to Gabriele Rafanelli and Patrizio Cantu. In 1992, he merged Cofragec's movie catalog with
UGC. The same year, he purchased the Formula 1 team
Ligier for an estimated 200 million
francs. The team, which had experienced a slump in recent years, had a successful
season in 1993, finishing in 5th place at the
Constructors' Championships, the team's best result since 1986. De Rouvre was forced to sell the team to
Flavio Briatore in early 1994 due to his legal problems. In
1995, he lost his reelection campaign as mayor of Chaumont. ==Legal issues==
