Austin Rivers Buys $300k Ferrari After $35 Mil Contract

Spend it if ya got it, right??

Austin Rivers would make Tom Haverford proud -- dropping some serious cash on a sick new Ferrari ... right after signing his 3-year, $35 MILLION contract with the L.A. Clippers.

TREAT YO'SELF!!!

Check out Austin's pimped out Ferrari F12Berlinetta -- which usually starts above $300,000!!!

But Austin's car is special ... he took it to the guys at Ultimate Auto in Orlando who outfitted the whip in a full matte metallic charcoal wrap, custom wheels and more. We're told the upgrades cost around $25k.

FYI, the Ferrari F12Berlinetta reportedly goes from 0 to 60 in 3.1 seconds and can hit speeds faster than 211 MPH!!!!

Austin ... be safe dude.
