Calvin Harris -- Damn Near Rips Door Off His SUV!!

Calvin Harris is in the market for something new -- a door on his luxury SUV, after nearly destroying his ride ... all in front of cameras.

Calvin was leaving his Bev Hills gym on Monday when he started backing up his Range Rover, but had no clue his back door was still open. Check out the video ... this is gonna hurt, especially for Calvin.

Apparently, he went off on the bank of photogs who were waiting for him, saying they're the reason he jacked up his Range -- but later apologized for the tantrum.

Let's face it, Calvin can afford the repair. Or even a new vehicle altogether.
