Miley Cyrus can go from 0-60 in 5.3 seconds ... without a top on ... and all it cost her was a cool $127,000 ... TMZ has learned. Cyrus
dropped by a Mercedes Benz dealership in Encino, CA last week ... and
drove off the lot in a brand new white 2012 SL550 convertible.
Sources close to Miley tell us ... the former Disney star paid for the entire thing up front ... because she can.
The
best part ... Miley didn't even turn in her old car ... a bodyguard
drove it back to her pad so she could joyride in her new toy.
