Jake Paul Buys $421K Ferrari, Immediately Rips Donuts, Breaks Car

Jake Paul put some of his enormous fortune to good use, buying a brand new Ferrari for nearly half a million bucks ... AND THEN HE BROKE THE CAR THE SAME DAY!!

The Problem Child, very much living up to his nickname, hit up Ferrari Puerto Rico in San Juan ... where he spent $421K on the new, very rare whip.

The Ferrari 296 GTB is pretty amazing. It goes 0-60 MPH in 2.7 seconds, and 0-100 in 5.1 seconds. It does the standing quarter mile at 9.9 seconds and has a top speed of over 200 MPH.

26-year-old Paul documented the purchase in his latest vlog ... picking up the car, and putting it straight to the test.

Yeah, no breaking-in period here.

Jake took the Rari to an open parking lot, turned the wheel, and stomped on the gas ... executing a bunch of donuts.

The 296 GTB didn't like Paul's driving -- with just about every warning sign flashing on the dash, including a warning that simply said ... "go to dealer."

It's unclear if Jake got the supercar fixed ... or just parked it in the garage of his new $15+ million mansion.

The big purchase comes at a time when Jake's company, Betr, is taking off. In fact, the company was valued at $300 million during a recent round of funding.
