John Travolta's pricey vintage ride was ripped off over the weekend in Santa Monica.

The actor, who had stopped to check out cars at a Jaguar dealership, parked his 1970 Mercedes-Benz 280SL on the street ... and when he returned 10 minutes later, the car worth six-figures, was gone!

Santa Monica P.D. confirmed to X17online that the Mercedes is registered to Travolta. As for right now, police tell us there are no leads in the case.

Travolta's rep has yet to comment on the incident.
