Just weeks after dropping $127K on a Mercedes convertible, Miley Cyrus hit the streets looking for yet another sexy set of wheels ... ALL WITHOUT WEARING A BRA -- and TMZ has the bouncy video evidence.
Sources tell TMZ, Miley saw the panty-melting '69 Mustang Fastback marked "for sale" on the street in L.A. last week ... and quickly set up a time to check it out in person.
According to sources, the owner drove the car to Miley's house so she could take a closer look -- and she inspected the car inside and out ... wearing a pair of denim short-shorts, a vintage Beatles t-shirt, and ZERO lady support.
The car was on sale for $23,000 -- a steal if you ask us -- but in the end, we're told Miley passed on it ... because the price tag was a bit too high.
The perks of being famous.
