This is how I roll! Miley Cyrus treats herself to a $127k Mercedes Benz convertible (5 PHOTOS)

Hot wheels: Miley Cyrus with her new $127,000 Mercedes Benz SL550 convertible

Miley Cyrus has splashed out $127,000 on a new car.

The 19-year-old star visited a Mercedes Benz dealership in Encino, California, last week and paid cash for a new white 2012 SL550 convertible which goes from 0-60mph in just 5.3 seconds.

Miley drove home in her new vehicle, while her bodyguard got behind the wheel of her old car to drive it back to her house, according to TMZ.

However, Miley - who is dating her Last Song co-star Liam Hemsworth - may not be out driving for a while as the clumsy star has suffered a painful injury at home.

She tweeted yesterday: 'cracked my tail bone doing a front flip... on to the couch. thats like when i tripped over a pillow and broke my arm. #onlyme'

Miley is no stranger to fast cars - her first ever vehicle, which she was given when she was just 16 years old, was a Porsche.

However, the Hannah Montana star was unhappy with the sports car because it used to belong to her mother.

She said at the time: 'I do have a car. I took my mom's old car. I didn't get the one I wanted, but I got the old car which wasn't so bad because it was a Porsche. I suppose it was a pretty good hand me down.'

The singer-and-actress has also previously insisted she is very good driver.

She said: 'I'm a good driver but I make my mum a nervous wreck, which makes me nervous.

'I love driving, and I'm pretty good at it - I really am!'
