Tyga: Hand Over the Lambo! You're $400k in the Hole

Tyga and the repo man are getting real tight -- his car loan company's trying to liberate his Lamborghini and nearly $450k from his bank account.

According to docs obtained by TMZ, Tyga owes Choice Motor Credit $357,350.77 for not making payments on his 2013 Lambo Aventador ... and as a result, they want to take back the luxury ride.

Tyga should know the drill by now -- CMC says it already repo'd the rapper's 2014 Bentley Mulsanne back in February and sold it. However, Tyga's still on the hook for more than $91k on that whip.

He's gonna save a ton on car insurance.
