Kylie Jenner, 15, Gets $125,000 Mercedes Benz, Gives It A 'Spa Day'

Kylie Jenner is the proud owner of a Mercedes Benz G Wagon, and she's only 15!

The Keeping Up with the Kardashians  star was first spotted in the SUV -- average price is $125,000 -- a few months ago, and we've exclusively confirmed its her very own.

"giving my G Wagon a spa day!" the youngest of the Kardashian-Jenner clan posted on her Twitter page along with a pic of her vehicle getting a super posh wash and buff.

California issues Provisional Permits to drivers starting at age 15 1/2.  They can only operate a vehicle with a licensed driver over the age of 18 in the front passenger seat with them.

Assuming she passes her test, Kylie can get her California Driver License when she turns 16 on August 10.

We're sure mom Kris Jenner will throw a blow-out of a sweet 16 party for her youngest baby.  But what to get a girl who already has a $125,000 car?
