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 … 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.
The lesson — it”s good to be rich.
