The Situation -- Don't Worry, It's Only a Rental

The Situation sure looks pissed off about this mustard yellow Mustang being torn apart ... but TMZ has learned it was really no big deal.

The Sitch's manager (pictured above) tells us the car was only a rental -- and it was the manager's rental, not The Situation's. The manager tells us he was backing up the car and didn't notice the truck behind him had its lift down -- so when he hit the lift and tried to pull forward, it ripped the bumper almost clean off.

Let's hope he got the insurance.
