Iggy Azalea drives a hard bargain ... she's also now driving a 1962 Impala that Nick Young has given her as a parting gift.
We've learned that Iggy and Nick struck a deal ... he gets the engagement ring back and she gets the car she had given him for Xmas.
Here's the breakdown ... the ring is 10.43 carats, and reportedly valued at half a mil.
As for the whip ... a '62 Impala is a classic ... a cherry one can go for as much as $100k.
