Hollande has had a rough two weeks both personally and politically since glossy magazine Closer published pictures of him hopping off the back of a motor scooter, his head clad in a large black helmet, for an apparent rendezvous with actress Julie Gayet at an apartment near the presidential palace.
While most French voters say the president's love life is his own business, news of the affair has trended on social networks, prompting businesses to seek to tap in on the issue in their ads.
"Unseen. Unknown. Private cars, tinted windows. At prices this low, you should choose discretion," it said.
Another rental car company, Sixt, made a similar crack in a newspaper insert telling Hollande: "Mr President, next time avoid the scooter. Sixt rents cars with tinted windows."
