Chris Brown Outbids Tyga to Snag 500 HP Supercar ... FIRST!

Chris Brown wanted so badly to be the first kid on his block with a Rezvani Beast -- a 500 horsepower street-legal race car -- he paid an extra $35,000 to make it happen!A rep for Rezvani tells TMZ, Chris snagged the first Beast ever made -- sight unseen, mind you -- after ponying up $200,000 ... even though the list price is a mere $165k.
Usually the cars are handmade in about 12-14 weeks, but CB couldn't wait. The extra $35k guaranteed delivery of model 001 in just 2 weeks -- beating out his pal Tyga, who was also angling for one.
The Beast has no doors, no roof, weighs just 1,650 pounds and goes 0-60 mph in just 2.7 seconds -- and no, it doesn't come with a car seat.
