Kylie Jenner shows off her impressive collection of luxury vehicles on Instagram

When you're a billionaire, why have one luxury car when you could have seven?

That seems to be Kylie Jenner's line of thinking behind a photo she posted Friday of her massive luxury car collection.

Tucked away in the 21-year-old entrepreneur's picture was her new silver Rolls-Royce Phantom, valued at $450,000.

Kylie was pictured in a vibrant orange shirt dress that she left unbuttoned to highlight her prominent cleavage.

The dress hugged the 5ft6in reality star's hips while displaying her toned legs, which culminated in a pair of Versace heels with clear straps.
