Barton`s Cadillac breaks down again

London: Mischa Barton was left stranded in Los Angeles again after her vintage Cadillac broke down for the second time in as many months.

The `OC` star`s bright blue car failed to start, and she was left out on the roads by herself in the early hours of Thursday morning waiting for a tow truck, Contactmusic reported.

Barton also experienced car troubles last month when the same Cadillac failed to start following a shopping trip to The Grove mall and had to be towed away for repair.
