Justin Bieber's seeing red, but in this case it's a very good thing ... he got a brand new luxury whip dropped off at his luxury hotel.
JB's special delivery went down Friday at the Montage resort in Laguna Beach, CA, when a flatbed truck arrived with a brand new, custom Lamborghini Aventador ... with a price tag likely well over $500,000.
We're told the Biebs took some video and admired the flashy red sports car for a bit -- as did all the passersby -- before hopping in and taking the 730 horsepower ride for a test drive.
Hopefully Bieber didn't have to back the car into any tight spots or up any steep hills ... and we certainly hope this Lambo gets treated more kindly than his last one.
