Fun Fact -- JFK's granddaughter drives a Chevy Impala.
Funner Fact -- JFK's granddaughter allegedly smashed into another car with her Chevy Impala.
No So Fun Fact -- The alleged victim sued JFK's granddaughter ... along with her mother.
TMZ has learned ... Caroline Kennedy and her hot 24-year-old daughter Rose Schlossberg were named in a lawsuit by a man who claims Rose crashed into his Honda Civic on Wilshire Blvd. in L.A. back in August.
According to the lawsuit, filed in L.A. County Superior Court, the victim claims he suffered serious physical and mental injuries as a result of Rose's "negligent" and "careless" actions behind the wheel ... and demanded more than $25,000 in damages.
Caroline was not in the car -- but was named in the lawsuit because she is the legal owner of the vehicle.
But, this isn't your average never-ending car-crash lawsuit ... the victim's lawyer tells TMZ, they've already reached a settlement with Caroline and Rose's people ... and will take action to have the case dismissed ASAP.
The lawyer, a Democrat, tells us, “Everybody, including the Kennedys, and their insurance company, were very caring, understanding, ethical, and honest.”
He adds, "They were first rate people, we're very satisfied."
