Nick Young -- Iggy Won Xmas This Year ... I Can't Top Her Gift

If Christmas is a battlefield ... Nick Young is France -- 'cause he just surrendered in the war for the best Xmas gift after his GF Iggy Azalea hooked him up with a sick classic car.

The Lakers star was rollin' around L.A. in his brand new '62 Chevy Impala -- which Iggy delivered to him outside the Lakers facility Monday -- when we asked if it was even possible to top Iggy's gift.

The short answer ... no ... and Nick knows it -- admitting that she "won" the holiday gift exchange this year.
