TMZ has learned ... Charlie Sheen's car was not the only vehicle stolen early Tuesday and taken to Mulholland Drive.
We've learned another car was stolen from The Summit -- a nearby gated community where Britney Spears used to live.
We're told the vehicle from The Summit was not pushed over the cliff, but it was left at a lookout point near where Charlie's car was dumped.
Remember, 4 months ago, when Charlie's first car was stolen and dumped over Mulholland, other cars were vandalized and a Bentley was pushed over a nearby cliff.
We're told so far cops don't know if the two thefts are connected.
So much for gated communities ...
